I usually work with Cadence and this is the first time I use spice for
years. I have translated and spice model into spectre to simulate it
with cadence and I would like to compare the results with the original
model.

The file is a *.spi file. What should I do in order to place this
transistor into a schematic?

I know it is a very basic question but I tried doing it like I did
years ago and something goes wrong. The .slb file is missing.

I am using Orcad 9.2.

Thanks in advance.

Probably just change its extension to .LIB and then install as a
library; but post the contents of *.SPI here to be sure.

Well I have the same problem Jim and I tried changing the extension to .lib
and still it doesn't work. This International Rectifier site gives its spice
models in .spi format and it opens in a text editor. Could you please explain
how to add these lines to Orcad and make use of the component. I'll include
the spice file of this IGBT Irgp30b120kd-e.
