Verilog A to symbol

Shobhitkareer

Hi,

Im trying to make symbol using verilog A, the design is actually formed using 3 files; so in the beginning I have included the file using " 'include abd.vams" but while compling it seems that its to able read that file? One of the file is written in verilog-ams.

Am I missing any step?

Thank you in advance

  • Hi,

    I know its against forum rules, but I think this question will make more sense here. Please excuse this time.

    But if I have to do monte carlo simulation in this file how should I include the cds_inherited_parameter function, should it be in all the three file for the same parameter or including cds parameter in file L1 will be sufficient?

    Thank you

    warmest regards

    I would expect it would be in PCNFET rather than PCNFET_L1, but then again you didn't say what it is you're planning to statistically vary. The example (as you posted it before) had all instance parameters, whereas in this case you'd need at least one global parameter (which ends up being locally varied for mismatch) which is used within the model somewhere. See this article on how to define the parameters within a VerilogA model for Monte Carlo. Perhaps if you explained what you planned to vary, it would be easier to answer?

    Oh, and it would have been better to create a new thread and include a link to the original thread. This thread is already very long and so pity the poor reader who searches and finds this thread for (say) the monte carlo issue and then has to thread through the massive history above...

    Regards,

    Andrew.
