Element arrangement check device and printed circuit board design device |
摘要 |
An element placement check system for checking element placement on a printed wiring board having wiring by which a power supply terminal of an integrated circuit and a power supply decoupling element for the power supply terminal are connected on a mounting surface on which the integrated circuit is mounted, wherein the wiring is connected to a power supply plane for providing a direct current power supply to the power supply terminal through a power supply via hole, including: element distance detecting means detecting a first wire length between the power supply decoupling element and the power supply terminal; power supply via hole distance detecting means detecting a second wire length between the power supply via hole and the power supply terminal; and determination means determining a positional relationship of the power supply decoupling element and the power supply via hole to the power supply terminal based on the first and second wire lengths, thereby providing a check system and a printed wiring board design system capable of checking a connection sequence of a power supply decoupling element such as a bypass capacitor and the power supply via hole connected to the power supply plane feeding a direct current power supply to the power supply terminal as viewed from the power supply terminal of an integrated circuit.
