Hi,
I'm using encounter for a tape-out. I want to use QRC for higher accuracy. However, I think I need to tell the tool where the executable for QRC is. How do I do that? Modifying PATH variable didn't help. Is there a command to do that?
In addition, I know for static timing analysis, coupling capacitances are not extracted seperately with setExtractRCMode -coupled false command. However, when I do timeDesign with -si option, I see some negative slack. Since the block I'm working on is a timing critical one, I need to make sure timing is accurate. You think I should take signal integrity into account for timing analysis and optimization?
Thanks!
