Hello, people. I've just found an error in the models. Mismatch model parameters are turned on as default.

```*********** Default mc switches **********
**
.param
+  sw_stat_global = 1
+  sw_stat_mismatch = 1
**```

Is this really a bug?
The simulator will ignore the gauss distn unless MC sim is used. So this should not affect other sim results. Am I missing sth?

<@U01QTMG2K8R> <@U04KADRK45A> Please don’t use Google version. Please use Efabless version 

<@U04KADRK45A> Yes, it’s a bug in a very old version. Simulation results are affected by those switches and inconsistent between simulations.
