How to debug 'unknown device' message?


Mike Cowlishaw
 

Hello,

I'm experimenting with adding a custom model to use in SwitcherCADiii (I'm
adding a Max931, but with a 'DIP8' symbol and using the Spice model from
Maxim -- almost the same as an LTC1540). I have the symbol part working
(Ralph's guide was very useful, I have some experiences to add about the
semantics of PINs and their ordering if anyone interesting).

I'm now as far as having the model start to run, but just get a message box:

Spice error
Error: Unknown device type in: xu1 n003 n002 n001 0 n002 n002 out 0
max931.fam max931

(which just looks like the call to the subcircuit with the filename and
Value added). There's no additional information in the .log file.

Anyone know how I can get more detailed information on the unknown device
type, or do I just have to plough through the model 'by eye'?
