各位前辈:
请教一个问题
在ICC中derive_pg_connection -reconnect
后显示如下
otherpower nets:1506/1506
unconnect power pin:0/0
other ground nets :1506/1506
unconnect ground pin: 0/0
warningower connection/checking is skipped for 3010 power pins because the required power pin information connot
be found in logical libraries.
这个警告要管吗

不用管。
因为 ”unconnect power pin:0/0;unconnect ground pin: 0/0“表示都连上了。
-reconnect没用过,
谢谢了
在check_mv_design -verbose时
报warning :logical lib_cell XOR2P does not have power/ground pin definition.(MV-512)
这个警告也可忽略?
如果是低功耗设计,那是lib问题。
lib里要定义pg_pin.
如果是普通设计那就没关系。
了解了谢谢
