Simulating `input.scs' on linux at 5:41:21 PM, Tue Jun 20, 2006.

Error found by spectre during circuit read-in.
input.scs: NM0 is an instance of an undefined model pmos_tn.
input.scs: NM1 is an instance of an undefined model nmos_tn.

spectre terminated prematurely due to fatal error.

The above error from Spectra occur when trying to run the simulation on a inverter. I had already defined the model library from library manager as well as within spectre itself .

Could anyone who has a solution to the above please let me know thank you in advance.
 

model definition cadence

would anyone be kind enough to post this question inside Cadence Sourcelink?
 

cmi spectre

have you select the section
 

Cadence Spectre

Have you ever defined your the models of your active components in "model path" in the simulator.
Regarding to erro messages, the simulator doesn't recognize the models...
 

Re: Cadence Spectre

yes, you should add two model definition of pmos_tn/nmos_tn in input.scs file.
 

Cadence Spectre

different names in your schematic with the models
 

Re: Cadence Spectre

are you sure you have the models name in the schematic? i happened to me i couldn't save with the model names and .... error simulating....
 

Re: Cadence Spectre

MN0&MN1 define a model name pmos_tn&nmos_tn , you should have the same model name in model lib file.
 

Re: Cadence Spectre

just to get more idea , you may try to define model in the input file itself and see if it works ...(for those two transistors)
 

Re: Cadence Spectre

1) Check that if u have added model library and model file in ADE
2) Open the model file and check if there are models of pmos and nmos defined with names pmos_tn and nmos_tn
3) if u find the above than check if there are any sections defined in the model files and appropriately add the sections in ADE
 

Re: Cadence Spectre

From your error information, the problem is the path or format of model file is wrong. If your model path is wrong,according to rajanarender_suram's method, the error may be overcome!
