Montecarlo: how to exclude some circuitry. |
|
|
Hi,
I my testbench I use the same flip-flop as driver and load for the DUT
in order to have a better model of my driver and my load. When trying to
characterize some of the mismatch behaviours of my DUT, I would like the
driver and the load _not_ to be statistically variated, the DUT only. I
haven't seen such an option documented anywhere and wonder if it is
possible at all in spectre. Kind of the same as an lvsignore flag set on
a simulation resistance, except it would be called something else.

I've never heard of such an option, but you can change the transistor models
to point to some identical model with no statistical variations defined.
