Feature of the Month
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.

Tip of the Month
Randomizing model parameter values
Check out how to write a testbench that randomizes parameter values for each run using embedded Python (EmPy) expressions.
Primitive of the Month
sample
This primitive models a sample-and-hold circuit, sampling the input at the clock's rising edge and holding it.
XMODEL Release Updates
