Modeling a buffer with arbitrary rising and falling transition waveforms

Thought 'transition' primitive can produce only linear transitions? Check out how you can define its transition waveforms arbitrarily with an additional 'pwl_func' primitive.

Tip of the Month

Specifying a range of digital mode inputs in UDM mapping

Got familiar with simple modespec expressions like '==1'? Check out how to describe more general conditions for UDM mode bits.

Primitive of the Month

transition

This primitive can convert an xbit-type digital input to an xreal-type analog output with finite rise and fall times.
