    When adding varactor into circuit, virtuoso simulator tell an error

    hello! I am using cadence IC615 and MMSIM 12 with TSMC 65nm LP(OA, not CDB), in most cases they work well
    but when I add varactor in to circuit, the simulator tell an error below.
    (On another computer, IC51 and MMSIM unknown with TSMC 65nm LP(CDB, not OA) can run the same circuit with varactor and tell no errors, so I think it's configuration problem.)
    Could anyone help? Thanks!

    what talking this log: input.ahdlSimDB//bsource.va.bsource_1.ahdlcmi/Linux/../ahdlcmi.out ?

    Maybe you need to install some packages to the system
