摘要
介绍了ＡＳＩＣ 设计过程中电源、地压点个数的选择原则； 列出了芯片内部电源、地布线宽度的计算方法； 讨论了电源、地线在芯片上的走向；最后给出了设计实例。
The selecting principle for pad numbers of V DD and V SS in the course of designing ASIC is introduced; The calculating method for width of V DD and V SS routing is listed; V DD and V SS routings on chip are also discussed;and an ASIC designing is given.
