Verilog A code with lookup table

Gold

Hai,

I have a doubt in TFET based Mixer circuit design. Actually I have downloaded InAs TFET model generated by PennState University. This model is having verilog A code and lookup table for current and capacitance values. I am trying to use this model in cadence virtuoso. I did DC and AC analysis. Is it possible to find pss, pac analysis for mixer circuit using InAs TFET model?

Thank you.

  • This ought to be possible by using "D" as the control string for each of the dimensions (according to the VerilogAMS 2.4 LRM at least this should pick the closest value). However, if I compare that with the VerilogA documentation in the MMSIM/SPECTRE installation, it says there that it looks for the exact value - and this appears from a very quick experiment what it does in practice.

    I think you'll need to contact customer support to ask for this closest fit to be supported in Spectre. I can't find anyone who has asked for this so far.

    Regards,

    Andrew.
