How to set the model parameter STIMOD in simulation?

Alex Liao
Hi

The STIMOD is the LOD stress effect model selector. I can view this after any simulation by printing the model parameter in virtuoso ADE. But I have checked the modelfile.scs which is included in any simulation. It is BSIM4.5 and no such selector found in it. Is there anybody who knows how to set this STIMOD? If it is in print MODEL parameter, it should come from somewhere. Anyone who has knowledge and presents here is highly appreciated.

Thanks,

  • Andrew,

     I think I get the idea of your test code now. .

     Stimod =2 is set in a new model card. teststimod.scs is like input.scs in runSimilation(the input file). The first time I seeing the .scs made me relate it to a model file identically in .scs suffix. But it is a input file according to your opinion. You can see from my figure I have no results no warning and errors. If stimod is not able to be set, at least stimod = 0 should be printted out. Even using "spectre input.scs | grep stimod ", which is the default input file generated from ADE, stimod is not printted out.  Also if so, this proves it cannot be changed in BSIM4.5 version because using your command is exactly the same as runing simulation in ADE.

    But I still like to try your input file (teststimod.scs).

    Regards,
