Tip of the Month
Modeling MOSFETs operating in linear/triode region
Here is a tip on how to model transistors that behave as variable resistors.
Primitive of the Month
prbs_gen
This primitive generates a pseudo-random bit sequence, now with a new parameter 'seq_mode', defining whether the parallel stream is a MSB-first or LSB-first sequence.
XMODEL Release Updates
XMODEL 2022.08
This release adds a new 'seq_mode' parameter to the 'prbs_gen' primitive, and 'trig_mode' parameters to the 'meas_ber' and 'probe_ber' primitives.
