CSMC035工艺提供的astro milkyway数据,可以用在icc上吗?
我自己用的是ICC : Version D-2010.03-ICC-SP5-2 for amd64 -- Feb 01, 2011
需要作什么转化才能用吗?
可以reference lib都是milkyway,icc兼容的,没问题的
在做 ICC的时候,import_design之后,用check_library命令查看,提示如下问题:
Warning: List of pins missing in logic library (LIBCHK-212)

不知道是啥原因
ignore
check_library的信息就是看看,没啥太大用处
好像我用的库的类型与我做对比实验的库(成功derive_pg_connect)的类型不一样:
Library Type: Technology
Library Type: Technology, PG pin Based
前者是成功的,后者是失败的。
用report_cell_physical sel_pad -connections -verbose 来查看,不成功的那个,把VSSO/VSSQ/VDDO/VDDQ都当成signal pin了。
1)正确的

这种情况要如何处理,才能derive_pg_power成功呢?
pad的power不需要derive的,说不清,太累了
