Model of the Month
Modeling a digital phase interpolator with arbitrary INL/DNL characteristics
Adding nonlinear characteristics to the existing phase interpolator model is super easy. Just add a 'pwl_func' primitive.
Primitive of the Month
meas_max
This primitive is useful when checking whether an xreal-type signal is below a certain threshold over a time interval.
