Greetings all,

when designing a new circuit often I use the Pspice program included in the package Cadence 16.3
It works well, the problem is that many components are not included in its libraries, like e.g. the BFR96

Googling around, I found the Spice definitions for this component, and for many others, the problem
being that they are in a format different from that specific of the Cadence incarnation of Spice,
i.e. PSpice....

My question is : is anybody aware of a way to convert the commonly available Spice parameters, those
released by the transistors manufacturers, in a format palatable to Cadence PSpice ?

I suppose to not be the first to have encountered this problem, so a solution surely must be lying around..

FWIW, LTSpiceIV can read OrCAD/Cadence PSpice library files.

I've had mixed results using downloaded SPICE models and subs with LTSpice, if memory serves the likes of certain PSpice and OrCAD models have encrypted sections that don't work with LTSpiceIV. There is a very active LTSpice Yahoo Group here where your questions will be answered promptly. LTSpice is quite powerful - but know the limitations of SPICE in-general when dealing with analog/mixed-signal simulati

Linear Tech has a video on using 3rd-party models:


I don't know about "encrypted sections", as I've used the 16.5 PSpice libraries
directly without any problem. And as long as I follow the procedures outlined in
the video referenced above, I've not had any issues with other 3rd party models.

I agree that the Yahoo group is an excellent resource.
