Wiring design method and system for electronic wiring boards
First Claim
1. A wiring design system for designing wiring for parts on a wiring board, comprising:
- input means for inputting logical connection information on said parts on said wiring board and signal group information for handling said connection information as a signal group;
wiring processing means for determining a wiring path for said parts, said wiring processing means performing steps ofhandling said signal group as a wiring unit for a wiring path search and dividing said signal group into smaller groups, andarranging said divided smaller groups such that they run adjacent to one another; and
output means for outputting wiring path information on said wiring path determined by said wiring processing means.

Abstract
A wiring design system when applied to wiring boards having various wiring restrictions, has a rough wiring plan at the floor plan stage so as to complete a wiring design satisfying the wiring restrictions in a short period of time while evaluating the congestion degree of the wiring. Logical connection information for wiring parts and signal group information for handling the connection information is input as a signal group. The signal group is handled as a wiring unit for a wiring path search and the signal group is divided into smaller groups. An optimum path is then determined in such a way that the divided smaller groups run adjacent to one another whenever appropriate.

10. A wiring design method for designing wiring for parts on a wiring board, comprising:
-
a first step of inputting logical connection information for wiring said parts and signal group information for handling said connection information as a signal group; a second step of handling said signal group as a wiring unit for searching for a wiring path for said parts, and dividing said signal group into smaller groups; a third step of evaluating layout conditions of said parts on said wiring board or a congestion degree of wiring on said wiring board; a fourth step of changing a layout of said parts; and a fifth step of, by considering said layout conditions of said parts on said wiring board or said congestion degree of said wiring on said wiring board, determining an optimum path in such a way that said divided smaller groups run adjacent to one another, and obtaining wiring path information. - View Dependent Claims (11, 12)
