Monte Carlo simulation

whlinfei

Dear All,

 I have the schematic of a current matching circuit. I want to test how well the matching is using Monte Carlo simulation?

However I couldn't find it in Spectra analysis panel.

Can anyone help me with it? Or provide any other solution to find out how the matching will be in the layout simulation or in the real fabrication?

thanks  a lot.  I use IBM 130nm process.

 Best Regards,

Linfei

  • Hi Linfei,

    It's rather hard for me to point you at where in the PDK/model documentation it covers this since I don't have access to the IBM PDK. Better for you to ask your technology provider (IBM?).

    Are you seeing any variation at all if you use "mismatch only"? If not, it may be that you're not using the right set of models; for mismatch the models need to be within subckts. There's a good explanation of this both on sourcelink and www.designersguide.org (I think in the modelling section) in a paper of monte carlo modelling.
