Hi all,
I want to plot monte carlo samples using FinFET 7nm PDK (from PTM.asm) in cadence spectre.
But i am getting the error:
"mc1: Attempt to run Monte Carlo analysis with process and mismatch variations, but no variations were specified in the statistics block."
How to solve it?
No, Monter Carlo Statistical Simulation needs process Variations Information for each Process Variable. You cannot do that by yourself, the Foundry can do only.
You could fake it if you understood process control limits
and correlations, but good luck getting that.
What you could do is put "k params" onto any model
param you think represents significant variation and
loop or loop-random, those values. If you are after
go / no-go test or datasheet limits, that's how we used
to roll before getting all Monte about every little thing.
