with the development of CMOS, the variation also become bigger.
so how to treat with the variation is a big issue for the IC designer.
I think that this is a good book even if you maybe at now don't meet the issue.
chip interconnect
Very interesting book.
As IC clock speed gets faster, more physical limitation on full-chip clock distribution is observed. How to mitigate this effect becomes more challenging. If you focus on mixed-mode design, this topic is good for studying.
Anyway, thanks for kind sharing
