大牛们:
我在ICC里run primerail的时候,提示说:
Rail Analysis:total power ports:19901.1655 power ports have no PG connection
PG network segment 1 is not connect to any std cell.
PG network segment 2 is not connect to any std cell.
PG network segment 3 is not connect to any std cell.
.
.
.
PG network segment 1898 is not connect to any std cell
我检查了design,PG都连上了的。
有没有人知道这是怎么回事?PG network segment 是啥意思?具体指的是哪里?
谢谢

有没有做place啊
做了的,这个报告是基于做完CTS出的,
奇怪的是做了post_opt以后,再跑Rrimerail,就没有这个错了
你好,请问你有没有学习PrimeRail教程啊?
try pg connect
