Hi everyone,

-----This issue deals with pspice complaining about an undefined
subcircuit-----

I brought in the model of a wideband transistor model from Phillips
Semiconductor (BFG series). Then, performed the following:

1. In the Model Editor of Pspice (Orcad student version 9.1), I
imported the files that I had downloaded into the model editor (and
saved in a directory. The downloaded files had the following names:
--- BFG10_SPICE.PRM and BFG10_SPICE
1a. While in the model editor I opened a NEW file and then using the
MODEL-->IMPORT menu options I brought in the BFG10_SPICE.PRM file.

1b. I then saved the file and was prompted to save it under Userlib
directory, which I did. I named it QBFG10-x.lib


2. I opened to Capture and wanted to palce this new part in the
schematic.
The "PLace Part" opened up and I added the new library which had the
name BFG10.olb.

3. I placed the part and then run the simulation. The error message
returned was that "subcircuit used by U7 is undefined".

Please advise what I am doing wrong and how to correct it.

Thanks

Martin.

Capture *sucks* so I can't comment on the symbol mechanism. But does
your *device* library contain a subcircuit declaration:

..SUBCKT BFG10 <nodes>
|
|
components
|
|
..ENDS BFG10
