QSPICE Circuit Simulation: A Spicy Discussion with Mike Engelhardt

Moore's Lobby: Where engineers talk all about circuits

If you are interested in electronics, history, or simple amazing stories, you will enjoy this podcast interview with our Moore’s Lobby host, Daniel Bogdanoff. Mike Engelhardt has been developing simulation tools since 1975. He is best known for creating LTspice, which is believed to be the most widely distributed and used SPICE analog electronic circuit simulator in the world.

Recently, he realized that he could take advantage of the massive improvements in both hardware and software to develop a radically improved circuit simulation engine; thus, QSPICE was born. Engelhardt explains how he created a better SPICE tool that could dramatically increase simulation speed while simultaneously improving functionality, accuracy, and reliability.

As you will hear, Mike’s amazing career includes developing simulation tools for applications as diverse as scanning electron microscopes and locating underground petroleum deposits. Here are a few more teasers about what you will hear in this far-ranging discussion with Engelhardt:

-The biggest early roadblock to simulation adoption in the EE world.

-Why simulations are more important than hardware to an engineer.

-The importance of time-domain simulation.

-Insights into QSPICE for power simulation of wide bandgap semiconductors like GaN and SiC.
