METHODS FOR VERIFYING AND DESIGNING CIRCUIT BOARD, DEVICES FOR THESE METHODS AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To automatically detect the corner part of a signal line where radiation noise may cause a trouble at the time of operation. SOLUTION: A circuit board verification method verities a circuit board having a signal line to be connected to an electronic part at the time of mounting. The electronic data of an electronic part supposed to be connected to a specific signal line among designed plural signal lines are extracted, electric energy to be applied to the specific signal line at the time of driving the circuit is calculated on the basis of the extracted electric data. When the calculated electric energy is more than a prescribed reference value, a corner part (e.g. the segment of pattern data connected at an angleθ) for changing the direction of wiring at a prescribed angle or less is detected from the pattern data of the specific signal line (steps ST10 to ST13) and the detected result is outputted (step ST16).
