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,

Alex

  • Andrew,

    In my ADE setting, I include only one model card (my_model_65STIMOD.scs) which is a copy of section of standard model card (section = tt and standard BSIM4 nch and pch part). I have manually added stimod = 2 to each section (50bins, 25 for nch, 25 for pch ). But after simulation I print model parameter of any device. The stimod is still unchanged. please see this .

    And I have tried your command "spectre teststimod.scs | grep stimod" and replaced teststimod.scs to my_model_65STIMOD.scs. The result is .

    I think I have covered every case(50 bin) and no other model section or devices involved. The unchanged result confused me.
