now i connect a curcuit with the nmos source connected to the inductor (something like source follower). After running calibre lvs, I have ERC error which state like this:
ERC Rule: Flag Metal 1 Nets That Have No Path to Power, Ground, or a Port:
but all my lvs pass except this. The above erc rule indicate the source of the nmos. May I know how to solve this problem.? can I ignore it?
you might want to define the Power and Ground nets in calibre settings, so that it knows what nes are they. Sometimes ERC errors provide useful information, sometimes they are just due to Calibre being confused...
