    Initial DC analysis extremely slow Reply
    I designed a serializer with a PLL. I can do post layout simulation with serializer or PLL separately. When I simulate the whole system, the spectre got stuck at the initial DC analysis. After print out "Trying 'homotopy = gmin' for nodesets.", there is nothing more to output after 5 hours running. It looks to me the initial DC analysis coverage slow. Anyone has any suggestions on that? Thanks a lot!
