DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention. In FIG. 1, the parts list file creation means 1 is PW
A parts list file 12 is created using the method shown below from the library 11 that stores definition information of parts mounted on the B wiring board.
Create.

The library 11 is a CAD computer that performs placement and wiring.
The way component information is described varies depending on the system based on the relationship between input and output files to the system. However, no matter what kind of library 11 is used, the parts list file creation means 1 can be configured to be reconfigured according to the library used by the user, so the versatility of the present invention will not be impaired. it is obvious.

The parts list file 12 includes, for example, the part name of each part stored in the library 11 as shown in FIG.
Stores information such as pin name assignment rules, pin name assignment direction, power/ground pin position, first pin position and pin generation interval. be done.

In order to generate this information, after storing the pin names and pin coordinates of all the pins in the component in a memory table, control is passed to the assignment rule generating means 8. The assignment rule generating means 8 first sorts the memory table in ascending order using the pin name as a key.

Next, the regularity of changes in pin names is examined from the order of the pin names as a result of sorting. For example, in the pin information A01 to A08 shown in FIG. 3, the first two characters do not change, and the third character is added from 1 to 8, so it can be seen that there is a regularity of A0[1-8]. By the way, there are various ways to express rules for expressing repetition rules, but here we will explain them according to the rule called regular expression, which is commonly used in operating systems such as UNIX and MS-DOS. ([ ] Parentheses mean that the characters within the parentheses change, and "a-b" means that the characters from the letter a to the letter b are generated sequentially.) Next, the sorted results Paying attention to the pin coordinates, the pins are arranged in one arrangement from the coordinates where either the X or Y coordinates are all the same,
If either the X or Y coordinates are expressed by two types of coordinates, it can be determined that there are two arrangements, and if both the X or Y coordinates are expressed by two types of coordinates, it can be determined that there are four arrangements, so it is possible to find the arrangement of the pins. can.

Next, regarding the direction in which pin names are assigned in the case of a two-array component, using FIG. 3 as an example, when comparing A01 and A02, it is found that the number increases in the X direction, and sequentially A04
After increasing in the X direction until A05, increasing in the Y direction, A
Since it can be easily determined that the number decreases in the X direction after 06, it can be seen that the direction is counterclockwise. At this time A0
The arrangement direction can be determined based on the difference between the coordinates of 1 and A02. When examining the direction in which pin names are given, the interval between pin occurrences can also be determined by determining the distances in the X and Y directions between two pins.

Although the present embodiment has been described above using two array components as an example, it can also be applied to other array components with some modification. Note that the present invention is not limited to this embodiment of the processing procedure.

When the processing of the assignment rule generation means 8 is completed, the parts list file creation means 1 erases the stored information on all the pins and passes control to the parts information reading means 2.

The parts information reading means 2 reads the parts list file 1.
2 and store all parts information in the memory table. The parts information indicating means 3 displays the contents of the memory table on an output device such as the display 21, and notifies the user of what kind of parts are available. The parts information selection means 4 inputs an instruction for a part to be reused from among the parts displayed by the parts information display means 3 or an instruction regarding the completion of modification of the parts information into an internal variable using an input device such as the key input device 22.

The selection completion determination means 5 is the part information selection means 4.
It is determined whether the set internal variable is an end instruction or not, and if it is an end instruction, the process goes to the new parts information generation means 7. If there is no termination instruction, the process goes to the parts information modification means 6. The parts information modification means 6 determines items to be corrected and new item contents of the parts information for the parts indicated by the internal variables set by the parts information selection means 4 using an input device such as the key input device 22, and stores them in the memory table. Update the contents of. Since the new parts information generation means 7 outputs a new parts registration file 13 for registering new parts in the library 11 used by the user, the output format differs depending on the type of library 11, similar to the parts list file creation means 1. However, by preparing a plurality of new parts information generating means 7, the versatility is not impaired. The new component registration file 13 stores component information that has been converted into a format in which the pin information in the component can be registered pin by pin in the library 11 by the assignment rule expansion means 9 which operates in the opposite manner to the assignment rule generation means 8.

An example of the operation of the attachment rule developing means 9 when the number of pins and the attachment rule of the component A in FIG. do.

First, since it is a two-array part, X=20, Y=
Since the arrangement direction is the X direction, 20 pins are generated from the 0 position, which is 1/2 of the number of pins, in the X direction. Next, assigning rules A01, A02, A03, A04, and A05 are sequentially defined from A[01-10] for the 5 pins generated.

Next, move by Y interval 50, X=20, Y
Generate the remaining 5 pins from the =0 position. For these 5 pins, the pin name assignment direction is counterclockwise, so assignment rule A [
01-10] remaining A06, A07, A0 obtained from
8, A09, A10 in the opposite direction A10, A09, A08
, A07, A06.

Through the above processing, new component information as shown in FIG. 4 is generated. The component library utilization design method of the present invention may be realized by an independent program, or may be incorporated into an interactive system or the like as one command.

[0021]

[Effects of the Invention] As explained above, the present invention can compress the information per component by setting rules for the repetition state of component pins, so it is possible to utilize the information by displaying each component one line at a time. This has the effect that parts can be easily found. In addition, the present invention has the effect that high-quality parts can be generated with only a small number of man-hours for corrections, as the electronic computer will position new pins, give pin names, etc. according to the rules simply by defining component pins using rules. be.
