Model of the Month

Modeling low-dropout (LDO) regulators

This application note demonstrates how to model two basic types of LDO regulators and simulate their key characteristics.

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.
