Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a design support device for displaying the connection status of divided integrated circuit drawings.

[0002]

2. Description of the Related Art In a conventional large-scale integrated circuit design support system, a logic circuit diagram is generally divided for each drawing from the viewpoint of functional design. Therefore, at the time of inputting the circuit diagram information into the computer system, the definition is performed in one divided drawing unit, various processing in the computer system is performed, and the output drawing is also defined as one unit defined at the input time. The circuit diagram is output to an output device such as a CRT.

In such a design support apparatus, the following two types of methods have been adopted to obtain connection information between drawings of a logic circuit diagram composed of a plurality of drawings. One is a method in which, after inputting a logic circuit diagram composed of a plurality of drawings, batch processing is performed, and connection information such as signal names, page numbers, connection status signal names, etc. is output in a list as shown in FIG. .. The other is a method of checking the crossing destination by referring to the crossing destination information addr1 (4) as shown in FIG.

[0004]

In the above-mentioned conventional design support apparatus, the output drawings are output in the unit of one drawing defined at the time of input. Therefore, it is difficult to clearly grasp the connection state between the drawings by the method of displaying the connection information as a list as shown in FIG. 9 and the method of referring to the destination information as shown in FIG. There was a flaw. Further, in addition to these two methods, the method of displaying a plurality of drawings having a connection relationship and obtaining the connection state by comparing the drawings has a problem that the connection information between the drawings is hidden by the overlapping of the drawings.

Therefore, the present invention has been made in view of such a conventional situation, and its object is a connection state between a plurality of drawings or a connection relation with a selected symbol or drawing. An object of the present invention is to provide a design support device capable of clearly grasping the connection state between drawings by displaying the connection state with drawings on one screen.

[0006]

In order to achieve the above-mentioned object, the present invention relates to a plurality of drawings constituting a divided and designed integrated circuit drawing, which are connected to a plurality of selected drawings or a selected symbol or drawing. Drawing name detecting means for detecting a drawing name of a related drawing, drawing information detecting means for detecting each drawing information, drawing arrangement position determining means for determining a display arrangement position of each drawing, and circuit diagram on each drawing Conversion rule detecting means for detecting a conversion rule for converting the layout position of the display layout position on the screen, graphic layout position storing means for storing the converted graphic layout position on the display screen, and information processing between drawings. The information processing means for performing drawings and the connection state display processing means for displaying the connection state diagram on the display screen are configured.

[0007]

With the above configuration, the design support apparatus according to the present invention extracts information regarding the connection state between the selected plurality of drawings and performs integrated display. Further, all the drawings in which the selected symbol or the symbol having the connection relationship with the selected drawing exist are detected, and they are integrated and displayed on one screen. Further, the connection information between the drawings is replaced with a connection pattern such as wiring to obtain each drawing information and the connection information between the drawings. Further, the overlapping drawings of the connected drawings are excluded from the display.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing the construction of an embodiment relating to the design support apparatus of the present invention. FIG. 2 is a flowchart showing a processing procedure of the design support device shown in FIG. An embodiment of the present invention will be described below with reference to these drawings. First, a menu for obtaining the connection relation between drawings is selected from the available menus of the design support device (ST
EP1). Command information, such as a keyboard, mouse, etc., that indicates whether the connection status between selected drawings is displayed (Case 1) or the connection status between a selected symbol or drawing that has a connection relationship with a drawing (Case 2) To the input unit 1 (STEP 2, 3).

The input command information and command argument information are analyzed by the command analysis section 2. The command argument includes the selected drawing name in the case of the connection status display of the selected multiple drawings, and the symbol name in the case of the connection status display of the selected symbol or drawings that have a connection relationship with the drawing. Or include the drawing name.

The command and command argument information analyzed by the command analysis unit 2 is passed to the processing routine corresponding to the command and command argument in the input processing unit 3. At this time, if the connection state display between the plurality of selected drawings is the purpose, it is passed to the drawing arrangement processing unit 5, and if the connection state display between the selected symbol or the drawing having a connection relationship with the purpose is the purpose, the connection is performed. It is passed to the drawing processing unit 4. If the purpose is to display the connection status between the selected plurality of drawings, the drawing name to be detected is already known, so the processing in the connection drawing processing unit 4 is not necessary.

When the purpose is to display the connection state between the selected symbol or the drawing having a connection relationship with the drawing, the connection drawing detection unit 4a causes the drawing in which the symbol having the connection relationship with the selected symbol exists or is selected. A drawing having a connection relationship with the created drawing is detected (STEP 4). The connection drawing display position determination unit 4b determines the layout position of the drawing in which the connection drawing detection unit 4a detects a symbol having a connection relationship with the symbol or the drawing having a connection relationship with the selected drawing (STEP 5). ).

Next, based on the command information processed by the input processing unit 3, the command argument information, and the information obtained by the connection drawing processing unit 4, the drawing layout processing unit 5 performs the layout process of the display drawing.

However, when the input command is the connection status display of the selected drawings, the selected drawing names and the command argument of the process by the connection drawing processing unit 4 are empty. When the input command is a connection status display of a drawing having a connection relationship with the selected symbol name or drawing name, the selected symbol name or drawing name and the command argument of the process by the connection drawing processing unit 4 are A drawing in which a symbol detected by the connection drawing detection unit 4a or a symbol having a connection relationship with the drawing exists, a connection drawing having a connection relationship with the selected drawing, and a display position determined by the connection drawing display position determination unit 4b Becomes

In the drawing layout processing section 5, each drawing name given as a command argument is detected by the drawing name detecting section 5a and stored in the drawing name storing section 5b (STEP 6). Also, the display layout position of each drawing in the connection status display diagram is
It is detected by the drawing placement position detection unit 5c and stored in the drawing placement position storage unit 5d. Further, the conversion rule detecting unit 5e obtains a rule for converting the display figure of each drawing into the layout display position in the integrated drawing, and stores the rule in the conversion rule storage unit 5f (STEP 7).

After the processing by the drawing placement processing unit 5, the drawing information processing unit 7 processes each piece of drawing information. Based on the drawing name stored in the drawing name storage unit 5b, the drawing information detection unit 7a detects each drawing information shown in the connection state display diagram (STEP 8). Each piece of drawing information of the detected plurality of drawings is stored in the drawing information storage unit 7b. Based on the display layout position information of each drawing stored in the drawing layout position storage unit 5d, the graphic layout conversion unit 7c converts the display layout position information of each drawing into the layout display position information in the connection state display diagram, and the graphic layout is performed. It is stored in the position storage unit 7d (STEP 9).

By the way, the information required for the connection status display diagram to be output is converted from the graphic display layout position information of all drawing information displayed in the connection status display diagram to the graphic layout position in the connection status display chart. All you have to do is to have the information. Therefore, by performing the above processing, the same information as one drawing information is held, and the connection state display diagram can be displayed on the output device.

Finally, on the basis of the drawing information and the display figure arrangement information stored in the drawing arrangement processing unit 5, the drawing display processing unit 9 performs the output processing of the connection state display drawing. First, the boundary frame of the drawing range on each drawing in which the graphic is arranged is displayed. This processing is based on the drawing arrangement position stored in the drawing arrangement position storage unit 5d, based on the drawing range display processing unit 9a.
(STEP 10).

Next, the inter-drawing information processing unit 9b performs a display process of the connection state across the drawings. An inter-drawing connection display portion by an annotation such as a page connector held in each drawing information and the inter-drawing connection information are detected by the inter-drawing connection information detecting unit 9
It is detected in b1 (STEP 11). The detected inter-drawing connection display portion and the inter-drawing connection information are converted into a pre-defined connection pattern for inter-drawing connection display by the inter-drawing connection information processing unit 9b2 (STEP 12). For example, the color brightness and the thickness of the connection are different from the connection pattern on the same drawing.

The converted inter-drawing connection information display portion and the inter-drawing connection information are edited by the inter-drawing connection information editing section 9b3 (STEP 13), and the inter-drawing connection information storage section 9b4.
Stored in. The stored display portion and its connection information are integrated with the information excluding the inter-drawing connection display portion in the connection state information editing portion 9c (STEP 14). The integrated inter-drawing connection information is subjected to display processing by the connection status graphic display processing unit 9d (STEP 15), and the output device 1 such as a CRT.
It is output to 0 (STEP 16).

FIG. 3 shows an example of a data structure for a circuit diagram stored in the graphic database 6 and designed to be divided into a plurality of drawings. To extract drawings that have a connection relationship with multiple drawings selected from this data structure, among the signals that have a connection relationship from the signal information linked to the signal name,
Only those existing on the selected multiple drawings are extracted.
The extracted drawings are given to the drawing information processing unit 9b. In addition, a drawing having a drawing having a connection relation with the selected symbol name or drawing is easily extracted from the signal name information.

The following is a practical example of the present invention. 4 and 5 are examples of displaying the connection state of a plurality of selected drawings. It is assumed that the drawing names Sheet1 and Sheet2 shown in FIGS. 4A and 4B are input and the arrangement position on the screen is designated so as to be as shown in (x1) of FIG. As a result, the connection state diagram is displayed on the same screen as shown in FIG. 5 by the design support device shown in FIG. As you can see from this figure, the symbols and_out4 and or_o which are connected
ut4 is connected with a thick line.
