LTspice Advanced


In this 2-day training workshop you will learn about the advanced use of LTspice for special purposes, especially for modelling (sub-)circuits. Part of the workshop is using LTspice functions for modelling a Pulse Width Modulator to drive a Half Bridge.

Also more advanced use of parameters – e.g. for statistics – is demonstrated. The use of Initial Conditions for (re)starting simulations is treated as well.

Furthermore some special techniques (FFTs and Averaged Modelling) are shown.

The course will help one to build a behavioural model of (own-designed) sub-circuits or (bought-in) ASICs.
