How to transfer spice model to spectre model

archive

I got following spice model for external MOSFET from the vandor, how can I import this into spectre to get the right simulation results.

I added "simulator lang=spice" line at the top, but it doesn't give me the right result.

MODEL REMOVED BY MODERATOR BECAUSE VENDOR MODEL REQUEST PAGE MAKES IT CLEAR THAT THE MODEL MAY NOT BE DISTRIBUTED.

    Steve,

    I removed the content of the model file that you posted above; it's NXP's model, so it should not be re-published on this forum.

    The fundamental problem is that it isn't really in SPICE syntax. First of all, there's no .SUBCKT header - I was expecting that there would be something like:

    .SUBCKT JBF862 1 2 3

    at the top. Secondly, there's a bunch of L, R and C components, but no instantiation of the model - it just defines the model. So no transistor instance. And finally it doesn't have a "." before the last line. I'm not that familiar with PSPICE (this may be a PSPICE model), despite it being a Cadence product, and so I tried using the new "pspice_include" statement that is in MMSIM13.1 to see if that helps. It didn't, because even then I would expect it to have a .SUBCKT statement. I suspect this is a file that can be read into Orcad Capture and then used within that environment (again, not my product area).

    So the best bet would probably be to contact customer support so we can explore this together in more detail; you might also need to contact the model vendor for some support.

    Kind Regards,

    Andrew.
