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,

  • Hi Andrew,

     My model card looks like this : 

    //model nch bsim4  { 

         1: type=n 

    + lmin=9.999997e-006-dxln   lmax=2.00001e-05          wmin=1e-005-dxwn

    + wmax=0.0009000001         version=4.5               gbmin=1.00e-12 // and there is no stimod, such keyword in model card.

    I tried to put  stimod = 2 in

    // model nch bsim4 stimod =2 {  //

    or in //model nch bsim4  {  1: type=n stimode =2 // or in

    or in//model nch bsim4  { 

         1: type=n 

    + stimod = 2 

    + lmin=9.999997e-006-dxln   lmax=2.00001e-05          wmin=1e-005-dxwn//

    And view info analysis (print model parameters), the stimod field is still = 0.

    So I think there is other way of setting this stimod.
