Monte carlo analysis problem

[barath_87]

I opened the Analog Statistical Analysis in cadence and gave the expression

VT("/voutp")
VT("/voutn")

Which are the o/p nodes of my comparator ...

I got an error when a ran the simulation in Analog Statistical Analysis

ERROR: "attempt to run maonte carlo analysis with process mismatches,but no process mismatches was specified in the statistical block"

How can i remove this error and perform the simulation......

PLs help

Thank you in advance

do you have process mismatch parameters when you start MC?

If the models from the fab don't have MC data, then you have to introduce it manually. In your netlist/sch, you parametrize the transistors you choose, set the distribution type, and after that you run MC. I work with Hspice, didn't use Cadence for a long time now, and can't tell exactly, except for the Hspice flow, but probably won't help too much.
