ICC报错求助

Error: The design has implicit supply nets in the supply sets. Please resolve them with real power/ground nets before you continue the flow.
Implicit power nets: pgd.primary.power
Implicit ground nets : pdg.primary.ground
还想问下ICC里做power grid有啥经验以及tcl的例子么。谢谢啦~

没用过唉，怎么调用ICC分析的啊

没人解答吗?

要update primary supply set, associate 到实际的supply: create_supply_setpdg.primary xxx -update
