Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an interactive wiring method for a wiring board.

[Prior Art] Conventionally, this type of interactive wiring system for wiring boards does not calculate or display the wiring length in units of nets (units of the same signal level) during interactive wiring.

[Problems to be Solved by the Invention] In the conventional interactive wiring method for wiring boards described above, the wiring length of each net is not calculated or displayed during interactive wiring, so the wiring length of the net cannot be calculated or displayed during interactive wiring. can't know.

For this reason, after wiring has been done, it may be necessary to re-route due to problems with the net wiring length.

In view of these inconveniences, it is an object of the present invention to provide an interactive wiring method for a wiring board that allows the wiring length of the net to be known during interactive wiring.

[Means for Solving the Problems] The interactive wiring method for a wiring board according to the present invention includes a wiring grid point data storage means for storing wiring grid point data to be connected, and an attribute (the presence or absence of wiring) of each wiring grid point. , via holes, parts bins, wiring prohibited points, etc.);
interactive wiring means for retrieving wiring grid point data to be connected from the wiring grid point data storage means and performing interactive wiring;
The present invention is characterized in that it includes a wire length calculation means for calculating a wire length using the grid attribute storage means during interactive wiring, and a display means for displaying the calculated wire length on a CRT or the like.

[Example] The present invention will now be described in detail with reference to one drawing.

Referring to FIG. 1, a wiring grid point 1 has a memory means 1.

The positional data of the wiring grid points (starting point, ending point) to be connected and the corresponding net name are stored in the table format shown in FIG. 2.

The grid attribute storage means 3 stores the attributes of all grid points on the R board, that is, whether it is a wiring grid that can be routed (empty) or a wiring grid that cannot be routed (wiring prohibited or already wired), and stores "0° or ", respectively. 1'' and pointer information indicating that it is used in net units is stored in a table format as shown in FIG.

In addition to the above-mentioned examples, the attributes may include via holes, component pins, and the like.

The wiring data storage means 5 stores a pointer indicating which grid in the grid attribute storage means 3 the starting point is as a result (or intermediate result) of the wiring of the net to be connected in the wiring grid point data storage means 1. This is added to the contents of the lattice point data storage means 1, and is stored in a table format as shown in FIG.

The interactive wiring means 2 retrieves data to be wired to the net 111 from the wiring grid point data storage means 1, and performs wiring between the two points in an interactive manner using a CRT.

Along with the progress of interactive wiring in the interactive wiring means 2, the wiring length calculation means 4 accesses the grid attribute storage means 3 from the pointer of the contents stored in the wiring data storage means 5, and calculates the grid points used for wiring. By counting 2
Calculate the wiring length between points.

It is sent to the display means 6. The display means 6 displays the net name and its wiring length at a predetermined position on the CRT.

[Effects of the Invention] As explained above, the present invention has the advantage that the net 11
Knowing the wiring length at each position can be useful in finding the optimal wiring route for dialogue wiring.
