Introducing UDM mode specification expressions
If you found MODELZEN running too exhaustive characterizations for user-defined models (UDMs), this new feature can make it significantly faster by constraining the mode bit values.

Randomizing model parameter values
Check out how to write a testbench that randomizes parameter values for each run using embedded Python (EmPy) expressions.
sample
This primitive models a sample-and-hold circuit, sampling the input at the clock's rising edge and holding it.
2021.12 Release
This release introduces the UDM mode specification expressions and adds new functions for generating random numbers from Poisson, binomial, and gamma distributions.
