プリント基板設計CADシステム
Document Type and Number:
Japanese Patent JP4071351
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To efficiently execute part arrangement work by calculating a part where an interaction of a bypass capacitor does not reach on a printed circuit and a bypass capacitor is in short and displaying the area of the shortage part. SOLUTION: An unneeded bypass capacitor list display controlling part 18 displays, outputs and controls a list of extra (excessive) bypass capacitors extracted by a bypass capacitor display processing routine (PF) using an unneeded bypass capacitor judgement processing table (TD). A valid range display image of a power supply area that follows an instruction of an operation inputting part 13 is selectively shown and outputted in valid range display images 19A and 18A of a bypass capacitor which are respectively and selectively shown and outputted in a displaying part 19 of a CAD. And, in such a case, a bypass capacitor shortage area highlight image 19A that highlights an area where a bypass capacitor is in short and an unneeded bypass capacitor display image 19B to which an unneeded bypass capacitor list 18b that presents extra (excessive) bypass capacitors are selectively shown and outputted.
