Modeling a finite-aperture clocked comparator with 'compare' primitive

Did you know the 'compare' primitive has a finite-aperture mode, which can model a clocked comparator with finite sampling bandwidth and regeneration time?

Primitive of the Month

vlimit

This primitive is equivalent to a pair of anti-parallel clamping diodes, which can keep the voltage between two circuit nodes within specified limits.

XMODEL Release Updates
