大家好,我在做一个BLOCK,属于同一个POWER DOMAIN,里面有LEVEL SHIFTER,这种情况需要UPF吗?现在给过来的DATA没有UPF,这些LEVEL SHIFTER老是报很多 LIBSETUP-001 的WARNING:
cell %s(%s) was constrained to operate under the operating condition %s, but the library cell %s matching this characterization has not been used. Instead, library cell %s from %s:%s (voltage = %s, process = %s, temperature = %s) has been used. %s
然后是 LIBSETUP-001A,B,C;最后来个汇总:
Error: A total of 57 operating condition problems (LIBSETUP-001) have bee detected
我原以为手工接好POWER就可以把上面的忽略了,结果在 CTS 的时候就做不下去了,无论哪个OPT的COMMAND:CTS PRELUDE FAILED。请问这种情况一般的流程是怎样的? |
