  • Hi Umar,

    Careful, it may not be wise to post proprietary/copyrighted models on a public forum.

    Most of the SPICE syntax I see should run as is.  You will need to adjust the Diode syntax a bit.  Check your Espice syntax manual for help.  You could also convert the Resistors that use a .Model to a one-line "R" statement.  But the rest of the syntax looks fine.

    Once adjusted, paste the text into an N-terminal black box model for use in SigXp.  There's help on that in the manual, or you can simply clone one out of the default library.

    Donald
