带upf文件的dc综合报错The target library does not contain an inverter.

SGengiant

具体的：


Error: The target_library does not contain an inverter characterized for operating condition (voltage = 1.080000V, process = 1.000000, temperature = 0.000000). (MV-006)
This problem occurred at:
    <top design>
Error: The target_library does not contain an inverter characterized for operating condition (voltage = 0.864000V, process = 1.000000, temperature = 0.000000). (MV-006)
This problem occurred at:
Error: The target library does not contain an inverter.
        An inverter is required for mapping. (OPT-101)


请问各位大佬这种问题该从何处修改呢，刚开始接触upf设计，无从下手...

printvar target_library

printvar target_library

好像就是引用target library的问题，我还想请教一下，是不是综合时会有包括isolation cell 、level shifter cell等低功耗单元的专有library，必须引用上才能完成综合，否则还是会报warning等信息？

大佬 我最近也碰到了一样的问题，不知道怎么解决，请问当时您是怎么修改的呢。我是target library里面放了std cell library和装有isolation cell、shifter 等低功耗的library，load upf之后，再insert mv cell的时候报出和你特别类似的error：

Error: The target_library does not contain an inverter characterized for operating condition (voltage = 0.810000V, process = 1.000000, temperature = -40.000000). (MV-006)

Error: The target library does not contain an inverter.

我的library default operation condition都是voltage 0.81，process 1以及temperature -40，不知道从哪下手改

upf是不是有高低压？把低压库也读进去就行了
如果没有高低压检查一下target_library吧？你是不是库没加全
