Wiring capacity evaluation system and wiring containment evaluation method

摘要

PROBLEM TO BE SOLVED: To improve design efficiency by evaluating wiring housability from a rough circuit constitution image with a substrate size, a design standard and a layer number, etc., as parameters before deciding the details of a circuit. ;SOLUTION: This system is composed of an interactive component arrangement part 1, a component information definition part 2, a substrate external shape definition part 3, a wiring housability calculation part 4, a substrate information definition part 5 and a virtual pin bare number calculation formula definition part 6. By such constitution, the wiring housability in the combination of various components is evaluated with the pin number and pin type of the components arranged on a printed board, the size and layer number of the printed board, the width and interval of a wiring pattern, a via hole diameter and a through-hole diameter as the parameters. Thus, the wiring housability is easily evaluated from the rough circuit constitution image. Also, since the wiring housability is evaluated without generating a detailed wiring pattern, the problem of requiring massive time for generating the wiring pattern is not generated.;COPYRIGHT: (C)1998,JPO
