Title: Spectre error with gpdk
Post by lahaha on Feb 2^nd, 2006, 6:48pm

I am a beginner of IC design.

When I use the gpdk to draw a schematic and use spectre to do the simulation, I got some errors in spectre.

si_inp: MN0 is an instance of an undefined model nmos1.
si_inp: MP0 is an instance of an undefined model pmos1.

Then I set the model included files for it. I got such errors

"..../models/nmos1.scs" 6: Illegal library definition found in netlist
"..../models/pmos1.scs" 6: Illegal library definition found in netlist
"..../models/pmos1.scs" 9: Duplicate name "Section"

I tried the gpdk.scs. I got the same kind of error

"...../models/gpdk.scs" 6:Illegal library definition found in netlist

I check the model file, the illegal library it said is gpdk.
Also I check the technology library of the library is gpdk.
Please help!

Can you describe how the model libraries have been set up in ADE? Also, if you could post the top part of the netlist (input.scs) which includes the model files, that would help.

Which version of the gpdk are you using, and which version of the Cadence IC tools?

I can't see any reason why you should be having these problems; I can only assume something isn't set up correctly, but for that I'd need to know what you have done so far...

Best Regards,

Andrew.
