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,

    By the way, my friend who is familiar with Hspice told me in HSPICE® Reference Manual; Version D-2010.12, December 2010;

    MOSFET Models Level 54 BSIM4 Model

    If VERSION>=4.3, the STI model is not dependent on STIMOD=0 or 1. In this case, the STI model is applied to the model similar to the UCB STI model. 

    He further explained "if your simulator uses a BSIM VERSION>=4.3 , STIMOD will automatically be reset to 1 , s. p. 482/506 , i.e. UCB's STI model usage will be enforced." 

     

    I don't know if this rule is applied in spectre. If so, anything I tried is in vain. BTW. I use tsmc65nm so the BSIM model is V4.5.

    Regards,
