Hi, all
I am characterizing a std library using encounter library characterizer, after the result comes out, the timing is almost the same with my reference lib, however, the internal power is much larger than the reference.
Here is the ref lib example of inv:
Here is my result from ELC:
Anyone knows why?
Thanks in advance!
