    Hi,
    has anybody tried to convert a spice netlist to spectre with spp in
    5.0.33? In that case, did you have the feeling that spp translated MOS
    transistors as if they have 5 pins and not 4? I see with 5.0.33 spp -h
    that it is possible to force 5 6 and 7 terminal mosfets, but no
    possibility to force 4 terminal devices.

    After upgrading from 4.4.6 to 5.0.33 the very same spice netlist did
    not convert right. Luckily I have 4.4.6 handy
    (http://modulefiles.sourceforge.net) and could do a quick rollback to
    get it properly converted.

    Anybody know what those extra terminals are used for?

    Without a specific example, it's hard to say. Did you log this as a customer
    support call? (that would be the right thing to do here, I think).

    I couldn't spot any obvious new problems with spp.

    Andrew.
