Conventionally, when making connections between the pins of a component, the paths that exist between the pins are discovered by a program through trial and error, or the patterns of all wiring paths from pin to pin are completely provided manually. I am taking one of the following. A method of discovering routes existing between pins by a program is such that once one route is found, the route search ends. [Literature
Rubin, F., “Chapter 6,” in Design
Automation of Digital Systems, Vol.1, MA
See Breuer, Ed., Prentice-Hall, 1972].
Therefore, when there are multiple possible routes, it is not possible to specify and determine a specific route among them. A method in which all wiring path patterns from pin to pin are provided completely by humans has a high possibility of incorrect wiring path patterns or wiring errors due to the manual input, and is not reliable. It is difficult to perform sophisticated designs.

In view of the above points, an object of the present invention is to adopt a method in which a person is given point data of a wiring route that he or she wants to pass, and a device, rather than a person, actually searches for a wiring route that passes through that point data. Therefore, quickly,
It is also possible to discover a desired wiring route without error.

The principle of the present invention will be explained in detail below. FIG. 1 is a block flow illustrating the principle of the present invention. In block 1, component pins to be connected and point data on the board to be routed as a wiring path are recognized. Now, let the component pins be A and B, and the point designated as the path be C i (i=1, 2, . . . , n). A,
The coordinate values of B and C i on the substrate are (A x , A y ), (B x ,
B y ), (C i x , C i y ). In block 2,
Coordinate values (A x , A y ), (B x , B y ), (C i x , C i y ) (i=
1, 2, . . . , n), calculate the area for wiring route search. First, coordinate values (A x , A y ) and (C 1 x ,
The rectangular area determined by the coordinates (C 1 x , C 1 y ) and (C 2 x , C 2 y ) is D 1 , and the rectangular area determined by the coordinates (C 1 x , C 2 y ) and (C 2 x , C 2 y ) is D 2 . C i x , C i y ) and (C x i+1 ,
C y i+1 ) and the rectangular area determined by D i+1 (i=1,
2,..., n-1). Finally, the coordinate values (C o x ,
The rectangular area determined by C o y ) and (B x , B y ) is
Let D o+1 . D i (i=1, 2, . . . , n+1) is called a wiring route search area. FIG. 2 is an example of a wiring route search area. When connecting pin 3' of component 1' and pin 4' of component 2', when points 5' to 7' are specified, the shaded areas 8' to 11' are the calculated wiring route search area. It is. Returning to FIG. 1, in block 3, a wiring path connecting component pins to be connected is searched within the wiring path search area determined in block 2. This search is performed by a device containing a search algorithm. In block 4, it is determined whether or not a wiring route has been discovered. If a wiring route is discovered, the route is stored in block 5, and if no wiring route is discovered, in block 6, the route is discovered. Display the impossible. The route search discovery is based on two facts: the component pins to be connected are recognized, and the wiring route search area is limited by calculating the wiring route area based on the point sequence. Since this is done using a device with a built-in search algorithm, it is possible to quickly and error-free find the desired wiring route.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 3 is a circuit block diagram of one embodiment of the present invention, which is composed of a storage device 10, an input/output device 20, a control device 30, a search device 40, and a storage device 50. The storage device 10 includes a connection data storage device 11, a component structure data storage device 12, a board structure data storage device 13, and registers 14, 15, and 16 for storing desired data elements.
The register 14 stores component pin data to be connected. The input/output device 20 is the input/output control device 21
and a register 22. The point data of the wiring route to be passed is read by the input/output control device 21 and stored in the register 22. The control device 30 includes a high speed memory 31, a control circuit 32, a synchronization circuit 33, a search area calculation device 33, and registers 35-37. High-speed memory 31 stores data in component structure data storage 12 and board structure data storage 13 through registers 15 and 16. The control circuit 32 includes the register 14 and the register 2.
The data stored in 2 is controlled and stored in register 36. The search area calculation device 34 reads the data in the high-speed memory via the register 35, and calculates the search area for the wiring route together with the data in the register 36. The search area calculation device reads the data stored in the register 36 one by one according to the synchronization clock generated by the synchronization circuit 33.

Lower left X coordinate value = Min (X i-1 , X i ) Lower left Y coordinate value = Min (Y i-1 , Y i ) Upper right X coordinate value = Max (X i-1 , X i ) Upper right Y coordinate value = Max(Y i-1 , Y i ) (1) The calculated search area is stored in the register 37. The search device 40 includes a path search device 41 and registers 42 and 43. With reference to the route search area data calculated by the control device 30 and stored in the register 37, the route search device 41
performs path search discovery between component pins to be connected. The route search device searches for a route from one point to another, and if there are multiple possible routes, it finds the one with the minimum length among them.
An example of a route search device is
The method disclosed in No. 129887 can be used. That is, it is possible to discover a path by tracing the propagation process using step signals on an electrical circuit network composed of a delay circuit and a detection circuit. If the route between the component pins is successfully discovered, "1" is stored in the register 42 and the data of the wiring route is stored in the register 43. If the route discovery is unsuccessful, "0" is stored in the register 42. The storage device 50 includes a determination circuit 51, a path storage device 52, and a register 53. If the data in the register 42 is “0”, the determination circuit 51 stores “0” in the register 53. Data in register 42 is “1”
In this case, the determination circuit stores "1" in the register 53, and the path storage device 52 receives the data in the register 43 through the determination circuit 51 and stores it. The present invention is not limited to the above example, but the present invention can be easily implemented by generating a wiring route search area by providing a route to be routed as a sequence of points, and performing a route search within this area.
