[0002]

2. Description of the Related Art The circuit design of a semiconductor integrated circuit is based on component information about components to be used and connection information between components.
It is composed of a component placement step of determining a component position and a wiring step of determining a wiring route between the placed components. Since the latter wiring step corresponds to the final step of circuit design, if there is a place where wiring is not possible, the design must be redone from the beginning.

The wiring process is a process of determining a wiring route between terminals which are arranged in advance according to the position of the component arranged in the component arrangement process. Among the wiring methods to determine the wiring route, there is an automatic wiring method described below, when performing the wiring process by the automatic wiring method, while avoiding obstacles between the wiring start terminal and the wiring end terminal, The wiring route is determined according to certain rules,
Wiring may not be completed by the current automatic wiring method alone. In that case, an interactive wiring method of manually inputting is adopted.

FIG. 12 is an example of a screen display of a personal computer when the automatic wiring method between two points is used. In FIG. 12A, a start point 601, an end point 602,
Obstacles 603 are displayed respectively. Among the two-point automatic wiring methods, there are known methods such as a maze method, a line segment search method, and a two-step wiring method for obtaining an optimum wiring route from predetermined wiring setting conditions. By specifying and inputting the point 601 and the end point 602,
It is possible to automatically obtain an optimum route, for example, a route with a minimum cost, without directly designating a bending point manually. The cost is calculated based on predetermined conditions such as the wiring length, the number of bends, and the number of times the wiring layer is changed. In FIG. 12B, the wiring route set after each point is designated is displayed. According to the automatic wiring method, the obstacle 6

2, an obstacle 703 and an intermediate point 704 are displayed respectively. In the general routing automatic wiring, the starting point 70
In addition to 1 and the end point 702, when an intermediate point 703 for instructing a rough route is designated and input at a required location, automatic wiring is performed under the condition that the intermediate point 703 is passed. In FIG. 13B, the wiring route set after each point is designated is displayed. According to the outline routing automatic wiring method, according to the specified start point, end point, arbitrary middle point,
It is possible to obtain an optimum wiring route that passes through the intermediate point.

Must be accurate, requires concentration of mind, eyes, arms, wrists,
Accompanied by finger fatigue.

In the two-point automatic wiring method, the starting point,
If the wiring route obtained by specifying the end point and input is different from the required wiring route, or if it is inconvenient due to the relationship with other wiring, delete the wiring route, start point, end again You must specify the point and enter it again. In this case, if the same start point and end point are designated, the wiring is set to the same route, so at least one of the start point and the end point must be changed. In order to specify the same start point and end point to obtain different wiring routes, it is necessary to change the predetermined condition of the cost calculation to obtain the minimum cost route, or switch to the manual wiring input method. There must be.

In the rough routing automatic wiring method, the rough routing must specify not only the start point and the end point, but also the approximate middle point of the wiring route required at an appropriate place. , There may be almost no difference from the labor of the manual wiring input method for designating all of the bending points.

FIG. 1 is a block diagram showing the configuration of a semi-automatic wiring device according to the present invention. The display unit 1 and the display unit 9, the designation input unit 2, the wiring object identifying unit 3, the shaping unit 5, the wiring setting unit 6, and the determination input unit 8 are connected to each other. The wiring object identifying means 3 includes a temporary wiring end object selecting means 4, and the wiring setting means 6 is a temporary wiring setting means 7.
Contains.

The display unit 1 displays wiring objects such as semiconductor elements and electronic parts for which wiring paths are set, and wiring obstacles which are areas where wiring cannot be set. Further, when attempting to set a wiring path between a plurality of wiring objects, wiring objects other than the plurality of wiring objects are also included in the wiring obstacle.

The designation input means 2 designates any one of the wiring objects for which a wiring route is to be set as a wiring start object which is a wiring start point, and in accordance with the designation of the wiring start object,
Either one of the wiring end object candidates selected as the wiring target object to be connected to the wiring start object based on the information given in advance is designated as the wiring end object, or the outline route of the required wiring path It is used when designating all or a part of the above by drawing a trajectory of the assumed general route.

The wiring end product candidate is to be connected to all the wiring objects which may be wiring end products corresponding to the wiring start product, that is, to be finally connected to the wiring start product. It includes all wiring objects. As will be described later, an end-of-wiring object for which a wiring route is to be set is designated from the end-of-wiring candidates, under certain conditions.

It is one of the major features of the semi-automatic wiring apparatus according to the present invention that all or a part of the schematic route of the wiring route is designated by drawing a trajectory of the assumed schematic route.

The wiring object identifying means 3 recognizes the positions of all the wiring objects, and connects to the wiring starting objects from among the wiring objects according to the designation of the wiring starting object based on the information given in advance. Wiring objects that identify all wiring end product candidates that should be processed and exclude wiring start products and temporary wiring end products selected from the wiring end product candidates or wiring end products specified from among the wiring end product candidates. Identified as a wiring obstacle,

The temporary wiring end product is selected from the identified wiring end product candidates by the temporary wiring end product selecting means 4 included in the wiring object identifying means 3 based on a predetermined selection condition. The predetermined selection condition is set, for example, from the conditions such as the wiring length when the wiring is set, the number of bends, and the number of times the wiring layer is changed, so that the wiring that can be set at the minimum cost is selected. If the selected temporary wiring end product is not appropriate for obtaining the wiring route to be set, the selection of the temporary wiring end product is canceled and the wiring end product is designated.

In the present specification, the recognition in the relative positional relationship with the finished wiring of the rough route designated in whole or in the partial rough route designated in part is referred to as "topological" recognition.

Here, "topologically" recognizing a route means not a coordinate as an actual numerical value, but a positional relationship in the vertical and horizontal directions with already arranged parts (wiring objects) and other wiring routes. It means to recognize only as information about the route. For example, something that is "above" a certain terminal will always collide with that terminal when continuously moving in the downward direction. Means that it cannot be migrated.

Wiring setting means 6
The setting of the wiring by (1) and the setting of the temporary wiring or the partial temporary wiring by the temporary wiring setting means 7 are performed based on a predetermined wiring condition. The setting of the predetermined wiring conditions is, for example, wiring that can be set at the minimum cost, temporary wiring, from the conditions such as the wiring length when the wiring is set, the number of bends, and the number of wiring layer changes,
The conditions are such that partial provisional wiring is set.

When the partial schematic route is designated by drawing an expected trajectory, partial temporary wiring is set for the other portions by the automatic wiring function of the wiring setting means 6 or the temporary wiring setting means 7. This is also one of the major features of the semi-automatic wiring device according to the present invention.

The decision inputting means 8 performs an input to decide acceptance / rejection of each of the provisional wiring end product, the provisional wiring, the partial provisional wiring, the shaping route, the partial shaping route, etc. set by the above-mentioned means.

The display means 9 causes the display unit 1 to display the temporary wiring, the partial temporary wiring, the shaping path, the partial shaping path, and the wiring finally decided to be adopted.

1, 102, and 103 are displayed. Here, the finally required wiring path is the wiring path 11 of FIG.
Assume that it is 3. Therefore, the wiring target object 101,
One of the wirings 102 is a wiring start product and the other is a wiring end product.

First, the wiring object 10 is set as the wiring starting object.
1 is designated by the designation input means 1 (step S10).
1). The wiring starter 101 is based on the information given in advance.
In accordance with the designation of, the wiring end object candidate 102 to be connected to the wiring start object 101 is identified by the wiring object identifying means 3 (step S102). It is assumed that the information given in advance includes information necessary for wiring design, such as types of wiring objects and connection relationships. When there are a plurality of wiring objects to be connected to the wiring starter 101, all of them are identified. Any one of the identified wiring end products is selected as a temporary wiring end product by the temporary wiring end product selection means 4 based on a predetermined selection condition (step S103).
Here, since the wiring end product candidate is only the wiring end product candidate 102, the temporary wiring end product 102 is selected, and the wiring target object 103 other than the wiring start product 101 and the temporary wiring end product 102 is selected.
Is identified as the wiring obstacle 103 by the wiring object identifying means 3 (step S104).

When the wiring start object 101 and the temporary wiring end object 102 are identified, the temporary wiring is set between the wiring start object 101 and the temporary wiring end object 102 by the temporary wiring setting means 7 based on a predetermined wiring condition. It is set (step S105). If this provisional wiring matches the required wiring path 113, the adoption decision is input (steps S106 and S1).
15) If they do not match, this is canceled (steps S106 and S107). For example, if a temporary wiring that passes under the wiring obstacle 103 is set, it does not match the required wiring path 113, so the temporary wiring must be canceled. When cancelled, it is determined whether or not the tentative wiring end product 102 selected by the tentative wiring end product selection means 4 is directly adopted as the wiring end product (step S108). Here, since the wiring end product candidate is only the wiring target object 102 and there is no room for selection, the wiring end product candidate 102 is directly adopted as the wiring end product 102 (steps S108 and S110). In the case where there are a plurality of wiring end product candidates, the first wiring setting between the wiring end product candidates other than the temporary wiring end product selected by the temporary wiring end product selecting unit 4 is the later wiring setting. If it is convenient from the above relationship, the wiring end product candidate is designated as the wiring end product (steps S108 and S1).
09). Here, the wiring objects other than the designated wiring end object 102 and wiring start object 101 are identified again as wiring obstacles (step S111).

After the wiring end product 102 is designated, the outline route 104 of the required wiring route 113 is drawn to draw the expected outline route 104 (step S11).
2, FIG. 7 (b)). When the semi-automatic wiring method according to the present invention is carried out using a personal computer, the rough path 104 is designated by, for example, using a mouse or the like to smoothly move the cursor on the display screen. The designated schematic path 104 is recognized in a relative positional relationship with the wiring target, that is, topologically (step S113). In this case, it is recognized that the display object 1 has passed over the wiring obstacle 103. Based on a predetermined shaping condition, the recognized rough route 104 is shaped into an optimal shaping route 113 under this shaping condition (step S114, FIGS. 7C to 7H).

A method of shaping the schematic route 104 of the wiring will be described with reference to FIGS. After topologically recognizing the rough path 104, an appropriate number of sample points are sampled under the topological condition. Schematic route 10 drawn
When sampling the points on 4, the topological conditions will necessarily be met, and here the sampling points 10
5, 106, 107, 108 are collected. This collection can be performed, for example, when the rough route 104 is designated, at a constant moving distance or at a constant time lapse.

After each sample point is collected, the partial shaping path 10 up to the first sample point 105 based on a predetermined shaping condition.
9 is set (FIG. 7D), and the sampling point 105 is set.
To the sample point 106 are set (FIG. 7E), where the partial shaping path 109 and the partial shaping path 110 are shaped to set the partial shaping path 111 (FIG. 7). (F)). After this, similarly, the partial shaping path 11 from the sampling point 106 to the sampling point 107
2 is set (FIG. 7G), a new partial shaping route is set from the partial shaping route 111 and the partial shaping route 112, and by repeating this shaping, the shaping route 113 is finally set. (FIG. 7 (h)). After confirming that the set shaping path 113 matches the required wiring path, the adoption decision is input (step S11).
5) The wiring route is completed (step S116).

Since a rough route is specified, it is usually impossible that the finally obtained shaping route does not match the required wiring route. However, when the shaping route is not adopted, it is not possible. Enter the hiring decision (step S11
5) Whether the rough route is designated again (step S11)
2) Whether the wiring end product is designated again (step S10)
9) Alternatively, the wiring start object may be designated again (step S101).

In the first embodiment of the above-described semi-automatic wiring method, after the wiring end product is designated (step S109), it is discriminated whether or not the designated wiring end product coincides with the tentative wiring end product. (Step S111), only when they do not match, provisional wiring may be set again based on a predetermined wiring condition (step S105).

A case of applying the first embodiment of the semi-automatic wiring method of FIG. 2 to the case of FIG. 8 will be described.

FIG. 8A shows four wiring objects 20.
1, 202, 203, and 204 are displayed. Here, it is assumed that the finally required wiring route is the wiring route 210 of FIG. This is a case where a wiring path that is slightly more complicated than that in the case of FIG. 7 is set, and common items will be briefly described or omitted. Wiring route 210
For setting, one of the wiring objects 201 and 202 is a wiring start object and the other is a wiring end object.

First, the wiring object 20 is set as a wiring starter.
1 is designated by the designation input means 1 (step S10).
1). The wiring starter 201 is based on the information given in advance.
According to the designation of, the wiring end object candidate 202 to be connected to the wiring start object 201 is identified by the wiring object identifying means 3 (step S102). When there are a plurality of wiring objects to be connected to the wiring starter 201, all of them are identified. Any one of the identified wiring end products is
Based on the predetermined selection condition, the provisional wiring end product selection unit 4 selects the provisional wiring end product (step S10).
3). Here, the wiring end product candidate is the wiring end product candidate 2
Since only 02, the tentative wiring end object 202 is selected, and the wiring objects 203 and 204 other than the wiring start object 201 and the tentative wiring end object 202 are identified as the wiring obstacles 203 and 204 by the wiring object identification means 3. (Step S10
4).

When the wiring starter 201 and the tentative wiring finisher 202 are identified, the tentative wiring setting means 7 creates a tentative wiring between the wiring starter 201 and the tentative wiring finisher 202 based on predetermined wiring conditions. It is set (step S105). If this provisional wiring matches the required wiring route 210, the adoption decision is input (steps S106 and S1).
15) If they do not match, this is canceled (steps S106 and S107). For example, if a tentative wiring that passes above or below the wiring obstacles 203 and 204 is set, the tentative wiring must be canceled because it does not match the required wiring path 210. When cancelled, it is determined whether or not the tentative wiring end product 202 selected by the tentative wiring end product selecting means 4 is directly adopted as the wiring end product (step S108). here,
Since the wiring end object candidate is only the wiring target object 202 and there is no choice, the wiring end object candidate 202 is directly adopted as the wiring end object 202 (step S10).
8, S110). In the case where there are a plurality of wiring end product candidates, the first wiring setting with the wiring end product candidates other than the temporary wiring end product selected by the temporary wiring end product selecting unit 4 is the later wiring setting. If it is convenient because of
The wiring end product candidate is designated as a wiring end product (steps S108 and S109). Here, the wiring objects except the designated wiring end object 202 and wiring start object 201 are identified again as wiring obstacles (step S11).
1).

After the wiring end product 202 is designated, the outline route 205 of the required wiring route 210 is drawn to draw the expected route 205 (step S11).
2, FIG. 8 (a). The designated schematic path 205 is recognized in a relative positional relationship with the wiring target, that is, topologically (step S113). In this case, on the display unit 1, the general route drawn from the wiring starter 201 passes above the wiring obstacle 203, passes between the wiring obstacle 203 and the wiring obstacle 204, and It is recognized that the wiring end object 202 is reached by passing below the obstacle 204. The recognized outline route 205 is shaped into the optimal shaping route 210 under this shaping condition based on a predetermined shaping condition (step S114).
The process of shaping is basically the same as the case of FIG. 7,
The partial shaping path is set in stages, and each time a new partial shaping path is set, the partial shaping path is shaped together with the previously set partial shaping path. By repeating this shaping, the shaping path 210 is finally set (see FIG. 8).
(B)-(f)).

After confirming that the set shaping route 210 matches the required wiring route, the decision to adopt is input (step S115), and the wiring route is completed (step S116).

As in the case of FIG. 7, since a rough route is specified, it is usually impossible that the finally obtained shaping route does not match the required wiring route.
If the shaping route is not adopted, the decision to reject is input (step S115), the rough route is designated again (step S112), the wiring end product is designated again (step S109), or the wiring is performed. The starting object may be designated again (step S101).

Also in the application example of the first embodiment of the semi-automatic wiring method of FIG. 8, after the wiring end product is designated (step S109), whether the designated wiring end product coincides with the temporary wiring end product. Identify whether or not (step S111),
Only when they do not match, again based on the predetermined wiring conditions,
Temporary wiring may be set (step S10).
5).

As described above, according to the first embodiment of the semi-automatic wiring method of the present invention, the rough route is designated only when the wiring route required by the automatic wiring method cannot be obtained. Moreover, the designation of the rough route can be easily performed by drawing a trajectory of the assumed rough route, and the required wiring route can be easily and surely obtained.

FIG. 3 is a flow chart showing a second embodiment of the semi-automatic wiring method according to the present invention. For the description of the second embodiment of the semi-automatic wiring method, the display example of the display unit 1 shown in FIG. 9 is used, and in the case of FIG.
A case where the second embodiment of the semi-automatic wiring method is applied will be described.

FIG. 9 shows three wiring objects 301 and 30.
2, 303 is displayed. Here, the wiring target 3
There is a plan to set the wiring in the direction from 03 to the wiring 305, and the wiring route finally required is the wiring route 306 (FIG. 9B). Therefore, one of the wiring objects 301 and 302 is a wiring start product and the other is a wiring end product.

First, the wiring object 30 is set as the wiring starting object.
1 is designated by the designation input means 1 (step S20).
1). Based on the information given in advance, the wiring starter 301
In accordance with the designation of, the wiring end object candidate 302 to be connected to the wiring start object 301 is identified by the wiring object identifying means 3 (step S202). When there are a plurality of wiring objects to be connected to the wiring starter 301, all of them are identified. Any one of the identified wiring end products is
Based on the predetermined selection condition, the provisional wiring end product selection unit 4 selects the provisional wiring end product (step S20).
3). Here, the wiring end product candidate is the wiring end product candidate 3.
02, only the temporary wiring end object 302 is selected, and the wiring target objects 303 other than the wiring start object 301 and the temporary wiring end object 302 are the wiring obstacles 30 by the wiring object identification means 3.
3 is identified (step S204).

When the wiring starter 301 and the temporary wiring end 302 are identified, the temporary wiring 304 is placed between the wiring starter 301 and the temporary wiring end 302 by the temporary wiring setting means 7 based on a predetermined wiring condition. Is set (step S20)
5). A wiring path 306 that requires this temporary wiring 304
If it does match, the adoption decision is input (steps S206 and S216), but if it does not match, it is canceled (steps S206 and S207). Temporary wiring 304
Is a minimum cost route set based on a predetermined wiring condition, which linearly connects the wiring start object 301 and the wiring end product 302, and does not match the required wiring route 306. 304 must be canceled. When cancelled, it is determined whether or not the tentative wiring end product 302 selected by the tentative wiring end product selection unit 4 is directly adopted as the wiring end product (step S20).
8). Here, since the wiring end object candidate is only the wiring target object 302 and there is no room for selection, the wiring end object candidate 302 is directly adopted as the wiring end object 302 (steps S208 and S210). In the case where there are a plurality of wiring end product candidates, the first wiring setting between the wiring end product candidates other than the temporary wiring end product selected by the temporary wiring end product selecting unit 4 is the later wiring setting. If it is convenient from the above relationship, the wiring end product candidate is designated as the wiring end product (steps S208 and S209). here,
The wiring objects excluding the designated wiring end object 302 and wiring start object 301 are identified again as wiring obstacles (step S211).

After the wiring end product 302 is designated, a partial rough route 313 is designated by drawing a part of the trajectory of the expected rough route of the required wiring route 306 (step S2).
12, FIG. 9 (d). However, this partial schematic route 313
The designation of is not definite and can be changed sequentially.
That is, when the cursor on the display screen is smoothly moved using a mouse of a personal computer or the like to specify the partial schematic route, the partial schematic route 313 is sequentially specified according to the movement of the cursor. Will be changed.

According to the outline of the second embodiment, a partial shaping route is set for a designated partial rough route, and a portion other than the portion for which the partial rough route is designated is set based on a predetermined wiring condition. The partial provisional wiring is set, and the adoption decision is input when the set partial shaping path and the partial provisional wiring match the required wiring path.

The cursor is moved to the partial schematic path 3 in FIG.
When the locus of 13 is drawn and moved, it passes through the points 307 and 308 of FIG. 9C. When the cursor is moved to the point 307, the wiring starter 301 to the point 307 are topologically recognized as a partial schematic route (step S213), and at the same time the partial shaping route 314 for the partial schematic route is set. (Step S21
4), partial provisional wiring 310 is set for the portion from the point 307 to the wiring end product 302 (step S21).
5). Since the partial shaping path 314 and the partial tentative wiring 310 do not match the required wiring path 306, the cursor must be moved to another position. FIG. 9C shows the partial tentative wirings 310, 311 and 312 which are set when the cursor is moved to the points 307, 308 and 309, respectively. Required wiring path 30
6 and the partial tentative wiring 310, 311, 312,
It can be seen that the positions of the points 307 and 309 are inappropriate and the position of the point 308 is the most appropriate.

Then, when the cursor is moved to the point 308 (FIGS. 9D and 9F), the wiring starter 301 to the point 308 are topologically recognized as a partial schematic path (step S213), and the portion concerned. At the same time as the partial shaping path 315 for the rough path is set (step S21
4), the partial provisional wiring 311 is set for the portion from the point 308 to the wiring end product 302 (step S21).
5). Since the partial shaping path 315 and the partial tentative wiring 311 match the required wiring path 306, if the decision to adopt the partial shaping path 315 and the partial tentative wiring 311 is input (step S216), it is necessary. The wiring path 306 is completed (step S217).

Since the partial schematic route can be specified and the partial shaping route and the partial tentative wiring can be confirmed, the cursor is moved until the required wiring route matches the partial shaping route and the partial tentative wiring. The required wiring path can be obtained.

In the first embodiment of the above-described semi-automatic wiring method, after the wiring end product is designated (step S209), it is discriminated whether or not the designated wiring end product coincides with the tentative wiring end product. (Step S211) Only when they do not match, provisional wiring may be set again based on a predetermined wiring condition (step S205).

As described above, according to the second embodiment of the semi-automatic wiring method of the present invention, the partial schematic route is designated only when the wiring route required by the automatic wiring method cannot be obtained. Moreover, it is possible to easily specify the partial schematic route by drawing a part of the trajectory of the assumed schematic route, so that the partial shaping route to be set and the partial provisional wiring are required to be the wiring route. Since it can be changed sequentially, the required wiring route can be easily and surely obtained.

FIG. 4 is a flow chart showing a third embodiment of the semi-automatic wiring method according to the present invention. For the description of the third embodiment of the semi-automatic wiring method, the display example of the display unit 1 shown in FIGS. 7 and 8 is used.

A case where the third embodiment of the semi-automatic wiring method of FIG. 4 is applied to the case of FIG. 7 will be described.

FIG. 7A shows three wiring objects 10.
1, 102, and 103 are displayed. Here, the finally required wiring path is the wiring path 11 of FIG.
Assume that it is 3. Therefore, the wiring target object 101,
One of the wirings 102 is a wiring start product and the other is a wiring end product.

First, the wiring object 10 is set as a wiring starter.
1 is designated by the designation input means 1 (step S30).
1). The wiring starter 101 is based on the information given in advance.
In accordance with the designation of, the wiring end object candidate 102 to be connected to the wiring start object 101 is identified by the wiring object identifying means 3 (step S302). It is assumed that the information given in advance includes information necessary for wiring design, such as types of wiring objects and connection relationships. When there are a plurality of wiring objects to be connected to the wiring starter 101, all of them are identified. Any one of the identified wiring end products is selected as a temporary wiring end product by the temporary wiring end product selection means 4 based on a predetermined selection condition (step S303).
Since the wiring end product candidate is only the wiring end product candidate 102, the tentative wiring end product 102 is selected. Next, when the selected tentative wiring end product 102 is designated as a wiring end product or there are a plurality of wiring end product candidates,
If it is more convenient to first set the wiring with the wiring end product candidates other than the temporary wiring end product 102 selected by the temporary wiring end product selection unit 4 in view of the later wiring setting, The wiring end product candidate is designated as the wiring end product.
Here, the tentative wiring end product 102 is designated as the wiring end product 102 (step S304). According to this specification,
The wiring object 103 other than the wiring start object 101 and the wiring end object 102 is the wiring obstacle 10 by the wiring object identification means 3.
3 is identified (step S305).

When the wiring starter 101 and the wiring finisher 102 are identified, the temporary wiring setting means 7 sets a temporary wiring between the wiring starter 101 and the wiring finisher 102 based on a predetermined wiring condition. (Step S306). If this temporary wiring matches the required wiring path 113,
Input the decision to hire (steps S307, S31
2) If it does not match, cancel it (step S).
307, S308). For example, if a temporary wiring that passes under the wiring obstacle 103 is set, it does not match the required wiring path 113, so the temporary wiring must be canceled.

In the third embodiment of the semi-automatic wiring method according to the present invention, since the designation of the wiring finish object 102 has already been decided, the designated wiring start object 101 and wiring termination object 102 are Of the required wiring path 113,
Draw an expected trajectory of the rough path 104 and draw the rough path 10
4 is designated (step S309, FIG. 7B). The designated schematic path 104 is recognized in a relative positional relationship with the wiring target, that is, topologically (step S310). In this case, it is recognized that the display object 1 has passed over the wiring obstacle 103. Based on a predetermined shaping condition, the recognized rough route 104 is shaped into an optimal shaping route 113 under this shaping condition (step S311, FIGS. 7C to 7H).

The shaping is performed by the same procedure as the shaping method described in the first embodiment, and finally, the shaping path 113 is formed.
Is set (FIG. 7 (h)). Set shaping path 11
3 confirms that the wiring route matches the required wiring route, and inputs the decision of adoption (step S312), and the wiring route is completed (step S313).

Since the rough route is specified, it is usually impossible that the finally obtained shaping route does not match the required wiring route. However, when the shaping route is not adopted, it is not possible. Enter the hiring decision (step S31
2) Whether the rough route is designated again (step S30)
9) Whether the wiring end product is designated again (step S30)
4) Alternatively, the wiring start object may be designated again (step S301).

A case where the third embodiment of the semi-automatic wiring method of FIG. 4 is applied to the case of FIG. 8 will be described.

FIG. 8A shows four wiring objects 20.
1, 202, 203, and 204 are displayed. Here, it is assumed that the finally required wiring route is the wiring route 210 of FIG. This is a case where a wiring path that is slightly more complicated than that in the case of FIG. 7 is set, and common items will be briefly described or omitted. Wiring route 210
For setting, one of the wiring objects 201 and 202 is a wiring start object and the other is a wiring end object.

First, the wiring object 20 is set as a wiring starter.

In accordance with the designation of, the wiring end object candidate 202 to be connected to the wiring start object 201 is identified by the wiring object identifying means 3 (step S302). When there are a plurality of wiring objects to be connected to the wiring starter 201, all of them are identified. Any one of the identified wiring end products is
Based on the predetermined selection condition, the provisional wiring end product selection unit 4 selects the provisional wiring end product (step S30).
3). Since the wiring end product candidate is only the wiring end product candidate 202, the tentative wiring end product 202 is selected. Then, the selected tentative wiring end product 202 is designated as the wiring end product, or when there are a plurality of wiring end product candidates, the tentative wiring end product 202 selected by the tentative wiring end product selecting unit 4 is selected. If it is more convenient to perform the wiring setting first with other wiring end product candidates from the viewpoint of the later wiring setting, the wiring end product candidate is designated as the wiring end product. Here, the tentative wiring end product 202 is replaced with the wiring end product 202.
(Step S304). According to this designation, the wiring objects 203 and 204 other than the wiring start object 201 and the wiring end object 202 are identified as the wiring obstacles 203 and 204 by the wiring object identifying means 3 (step S).
305).

When the wiring starter 201 and the wiring finisher 202 are identified, the temporary wiring setting means 7 sets a temporary wiring between the wiring starter 201 and the wiring finisher 202 based on predetermined wiring conditions. (Step S306). If this temporary wiring matches the required wiring path 210,
Input the decision to hire (steps S307, S31
2) If it does not match, cancel it (step S).
307, S308). For example, wiring obstacles 203 and 2
If a provisional wiring that passes above or below 04 is set, it does not match the required wiring path 210, so the provisional wiring must be canceled.

Since the designation of the wiring end product 202 is already fixed, the designated wiring start product 201 and wiring end product 2 are designated.
For 02, the outline route 205 of the required wiring route 210 is drawn to specify the outline route 205 (step S309, FIG. 8A). The designated schematic path 205 is recognized in the relative positional relationship with the wiring target, that is, topologically (step S31).

Passing above, the wiring obstacle 203 and the wiring obstacle 204
It is recognized that the wire has passed between the path and the path, passed below the wiring obstacle 204, and reached the wiring end object 202. The recognized outline route 205 is shaped into the optimal shaping route 210 under this shaping condition based on a predetermined shaping condition (step S311). The process of shaping is basically the same as the case of FIG. 7, and the partial shaping route is set stepwise, and each time a new partial shaping route is set, the partial shaping route set before that is set. It will be shaped together with. By repeating this shaping, the shaping path 2 is finally obtained.
10 is set (FIGS. 8B to 8F).

After confirming that the set shaping route 210 matches the required wiring route, the decision to adopt is input (step S315), and the wiring route is completed.

As in the case of FIG. 7, since a rough route is specified, it is usually impossible that the finally obtained shaping route does not match the required wiring route.
If the shaping route is not adopted, the decision to reject is input (step S315), the rough route is designated again (step S312), or the wiring end product is designated again (step S309), or the wiring is performed. The start object may be designated again (step S301).

As described above, according to the third embodiment of the semi-automatic wiring method of the present invention, the rough route is designated only when the wiring route required by the automatic wiring method cannot be obtained. Moreover, the designation of the rough route can be easily performed by drawing a trajectory of the assumed rough route, and the required wiring route can be easily and surely obtained.

When there are a plurality of wiring objects to be connected to the wiring starter 301, all of them are identified. Any one of the identified wiring end products is
Based on a predetermined selection condition, the provisional wiring end product selection unit 4 selects the provisional wiring end product (step S40).
3). Since the wiring end product candidate is only the wiring end product candidate 302, the tentative wiring end product 302 is selected. Then, the selected tentative wiring end product 302 is designated as the wiring end product, or when there are a plurality of wiring end product candidates, the tentative wiring end product 302 selected by the tentative wiring end product selection means 4 is selected. If it is more convenient to perform the wiring setting first with other wiring end product candidates from the viewpoint of the later wiring setting, the wiring end product candidate is designated as the wiring end product. Here, the provisional wiring end product 302 is replaced with the wiring end product 302.

When the wiring starter 301 and the wiring finisher 302 are identified, the temporary wiring 304 is set between the wiring starter 301 and the wiring finisher 302 by the temporary wiring setting means 7 based on predetermined wiring conditions. (Step S406). If the provisional wiring 304 matches the required wiring route 306, the adoption decision is input (step S40).
7, S413), and if they do not match, this is canceled (steps S407, S408). The temporary wiring 304 is a minimum cost route set based on a predetermined wiring condition, linearly connects the wiring start product 301 and the wiring end product 302, and does not match the required wiring route 306. The temporary wiring 304 must be canceled.

Since the designation of the wiring end product 302 has already been decided, the designated wiring start product 301 and wiring end product 3 are designated.
02, a partial schematic route 313 is drawn by drawing a part of the trajectory of the expected schematic route of the required wiring route 306.
Is designated (step S409, FIG. 9D). However, the designation of the partial schematic route 313 is not definite and can be changed sequentially. That is, when the cursor on the display screen is smoothly moved using a mouse of a personal computer or the like to specify the partial schematic route, the partial schematic route 313 is sequentially specified according to the movement of the cursor. Will be changed.

Similar to the second embodiment, the outline of the fourth embodiment is such that a partial shaping path is set for a designated partial rough path, and a portion other than the portion where the partial rough path is designated. With regard to the above, the partial provisional wiring is set based on a predetermined wiring condition, and the adoption decision is input when the set partial shaping path and the partial provisional wiring match the required wiring path. .

The cursor is moved to the partial schematic path 3 in FIG.
When the locus of 13 is drawn and moved, it passes through the points 307 and 308 of FIG. 9C. When the cursor is moved to the point 307, the wiring starter 301 to the point 307 are topologically recognized as a partial schematic path (step S410), and at the same time the partial shaping path 314 for the partial schematic path is set. (Step S41
1), partial provisional wiring 310 is set for the portion from the point 307 to the wiring end product 302 (step S41).
2). Since the partial shaping path 314 and the partial tentative wiring 310 do not match the required wiring path 306, the cursor must be moved to another position. FIG. 9C shows the partial tentative wirings 310, 311 and 312 which are set when the cursor is moved to the points 307, 308 and 309, respectively. Required wiring path 30
6 and the partial tentative wiring 310, 311, 312,
It can be seen that the positions of the points 307 and 309 are inappropriate and the position of the point 308 is the most appropriate.

Then, when the cursor is moved to the point 308 (FIGS. 9 (d) and 9 (f)), the wiring starter 301 to the point 308 are topologically recognized as a partial schematic path (step S410). At the same time as the partial shaping route 315 for the rough route is set (step S41
1), the partial provisional wiring 311 is set for the portion from the point 308 to the wiring end product 302 (step S41).
2). Since the partial shaping path 315 and the partial tentative wiring 311 match the required wiring path 306, if the decision to adopt the partial shaping path 315 and the partial tentative wiring 311 is input (step S413), it is necessary. The wiring route 306 is completed (step S414).

Since the partial outline route can be specified and the partial shaping route and the partial tentative wiring can be confirmed, move the cursor until the required wiring route matches the partial shaping route and the partial tentative wiring. The required wiring path can be obtained.

As described above, according to the fourth embodiment of the semi-automatic wiring method of the present invention, the partial schematic route is designated only when the wiring route required by the automatic wiring method cannot be obtained. In addition, the partial rough route can be easily specified by drawing a part of the trajectory of the assumed rough route, so that the partial shaping route to be set and the partial provisional wiring are required. Since it can be changed sequentially, the required wiring route can be easily and surely obtained.

FIG. 6 is a flow chart showing a fifth embodiment of the semi-automatic wiring method according to the present invention. In order to explain the fifth embodiment of this semi-automatic wiring method, the display example of the display unit 1 shown in FIG. 10 is used, and in the case of FIG.
A case where the fifth embodiment of the semi-automatic wiring method in FIG. 6 is applied will be described.

FIG. 10 shows three wiring objects 401, 4
02 and 403 are displayed. Here, it is necessary to connect the three wiring objects to each other, and the wiring paths for the connection are the wiring paths 411 and 413 in FIG.
It must be a T-shaped wiring path consisting of

First, the wiring object 40 is set as the wiring starting object.
1 is designated by the designation input means 1 (step S60).
1). Based on the information given in advance, the wiring starter 401
According to the designation of, the wiring end object candidates 402 and 403 to be connected to the wiring start object 401 are identified by the wiring object identifying means 3 (step S602). As in this case, when there are a plurality of wiring objects to be connected to the wiring starter 401, all of them are identified. Any one of the identified wiring end products is selected as the temporary wiring end product by the temporary wiring end product selection means 4 based on a predetermined selection condition (step S603). Here, it is assumed that the temporary wiring end product 402 is selected from the wiring end product candidates 402 and 403. However, the selection of the tentative wiring end product is not definite, and may be changed in accordance with the designation of a partial schematic route that can be sequentially changed later.
After this selection, the wiring start object 401 and the wiring end object candidate 40
The wiring objects other than 2 and the tentative wiring end object 403 (which are still wiring end object candidates even after being selected as the tentative wiring end object) are regarded as wiring obstacles by the wiring object identification means 3. It is identified (step S604). FIG.
In this display example, there is no object identified as a wiring obstacle.

When the wiring starter 401 and the temporary wiring finisher 402 are identified, the temporary wiring 404 is provided between the wiring starter 401 and the temporary wiring finisher 402 by the temporary wiring setting means 7 based on a predetermined wiring condition. Is set (step S60
5). A wiring path 411 that requires this temporary wiring 404
And 413, or part of,
If the wiring setting after that is not inconvenient, the adoption decision is input (steps S606 and S61).
3), otherwise it is not adopted (step S60).
6). Here, the temporary wiring 404 is compared with the required wiring paths 411 and 413, and the temporary wiring 404 is not adopted. However, there is no need to perform any cancel operation.

In the fifth embodiment, partial rough routes are designated in order to obtain the required wiring routes 411 and 413. Also in this case, when implementing the allocation automatic wiring method, it is assumed that a personal computer is used,
The partial schematic route is performed by moving the cursor by operating the mouse or the like.

A partial schematic route is designated by drawing a part of the trajectory of the assumed schematic route of the wiring routes 411 and 413 required from the designated wiring starter 401 (step S607, FIG. 10B). )). However, as described above, the designation of the partial schematic route is not definite and can be changed sequentially. That is, when the cursor on the display screen is smoothly moved by using the mouse of the personal computer or the like to specify the partial schematic route, the partial schematic route is sequentially changed according to the movement of the cursor. Will be done.

Similar to the second embodiment, the outline of the fifth embodiment is such that a partial shaping path is set for a designated partial rough path, and a portion other than the portion for which the partial rough path is designated. With regard to the above, the partial provisional wiring is set based on a predetermined wiring condition, and the adoption decision is input when the set partial shaping path and the partial provisional wiring match the required wiring path. .

When the cursor is pulled out to the position of point 405 in FIG. 10B and stopped, the designated partial schematic route is topologically recognized according to the designation of the partial schematic route at this position (step In step S608, the provisional wiring end product selection unit 4 identifies whether or not it is necessary to change the provisional wiring end product selected according to the recognized partial schematic route (step S609). The identification as to whether or not this change is necessary is performed sequentially according to the designation of the partial schematic route to be changed sequentially. For the designation of the partial schematic route at the position at the point 405, the provisional wiring end product 402 is maintained as it is. The determination of this identification is performed according to the above-mentioned predetermined selection condition. When the temporary wiring end product is maintained, the wiring start product 401, the temporary wiring end product 402,
Depending on the designation of the partial schematic route at the position of the point 405,
The partial shaping path 406 is set (step S611),
The partial provisional wiring 407 is set (step S612).
It can be considered that the partial shaping path 406 and the partial provisional wiring 407 form a part of the required wiring paths 411 and 413, but the required wiring paths 411 and 413 are the same as the wiring path 411. It is composed of the wiring path 413, and there are no bending points in setting the wiring. On the other hand, if the partial shaping path 406 and the partial provisional wiring 407 are adopted, it means that the wiring setting already includes one bending point, and such a wiring setting method is costly. It becomes expensive. Therefore, the designation of the partial schematic route will be changed.

When the cursor is further moved to the position of point 408 and stopped (FIG. 10C),
According to the designation of the partial schematic route at this position, the designated partial schematic route is topologically recognized (step S60).
8) The temporary wiring finished product selecting unit 4 identifies whether or not the temporary wiring finished product selected according to the recognized partial schematic route needs to be changed (step S609). In this case, the provisional wiring end product 402 does not meet the predetermined selection condition due to the designation of the partial schematic route at the position of the point 408, and the provisional wiring end product selection means 4 needs to change the provisional wiring end product. Identified as being. Depending on this identification and the designation of the partial schematic route at point 408,
The provisional wiring end product 403 is newly selected from the wiring end product candidates.
However, based on a predetermined selection condition, the provisional wiring end product selection means 4
Is selected (step S610). When a new temporary wiring end product 403 is selected, the wiring start product 40
1, the partial shaping path 409 is set (step S611) and the partial temporary wiring 410 is set (step S612) in accordance with the designation of the partial schematic path at the positions of the temporary wiring end object 403 and the point 408. The partial shaping path 409 and the partial provisional wiring 410 are the same as the wiring path 411 among the wiring paths 411 and 413 that form the required wiring paths 411 and 413, and are considered to be adopted. Therefore, the adoption decision is input (step S613). As a result, the wiring path 411 is set (FIG. 10 (d)). At this point, it is considered that a part of the wiring route is completed (step S614), and the wiring starter 40
1, wiring end product candidates 402, 403, tentative wiring end product 40
The identification as 3 is released. However, in order to obtain the required wiring paths 411 and 413, it is necessary to further set the wiring path 413.

Therefore, the wiring object 402 is newly designated as the wiring start object by the designation input means 1 (step S601). Based on the information given in advance, according to the designation of the wiring starter 402, the wiring end object candidates 401 and 403 to be connected to the wiring starter 402 and the wiring route 411 are identified by the wiring object identifying means 3. (Step S
602). After this, usually, based on the predetermined selection conditions,
Although the temporary wiring end product is selected from the wiring end product candidates by the temporary wiring end product selection means, in this case, it is recognized that it is optimal to connect the wiring to the wiring route 411, and the wiring route 411 is recognized. Is selected as the temporary wiring end product.
That is, the wiring route that has already been set is also included in the wiring end product candidates, and the temporary wiring end product is selected (step S60).
3). After this selection, the wiring objects other than the wiring start object 401, the wiring end object candidates 402 and 403, and the tentative wiring end object 411 are identified as wiring obstacles by the wiring object identification means 3 (step S604). In the display example of FIG. 10, there is no object identified as a wiring obstacle.

Then, the temporary wiring 412 is set based on the predetermined wiring condition (step S605). This provisional wiring 412 matches the wiring path 413 among the wiring paths 411 and 413 that form the required wiring paths 411 and 413, and it is recognized that it should be adopted. Input (Step S61)
3). As a result, the wiring route 413 is set, and the required wiring routes 411 and 413 are completed (step S614, FIG. 10F).
