@User: It is something I'm working on refinining, but it does work. Capacitance parasitics are a given, as they just add extra components to the netlist. Resistive parasitics are the difficult one, as they modify the netlist. Magic does full R-C extraction, but it does so in a complicated way, generating and reading back information from a .sim file, which loses a number of key bits of information like what the substrate is. I hacked at the code a bit until it basically works except that you may have to do a search-and-replace on the final netlist to get the substrate back (this will be a real problem for layouts with isolated wells). I hope to have this properly fixed before the next shuttle run (ideally done this month).
