LTSpice

LTSpice is a popular simulation package. The successor to LTSpice is qspice, also programmed by the same developer. https://hackaday.com/2023/08/25/qspice-picks-up-where-ltspice-left-us/

Getting Started

• https://learn.sparkfun.com/tutorials/getting-started-with-ltspice/all - some videos here, and they also link to the LT youtube playlist. The forum is DOA, don't bother clicking that. Some high frequency noise on the sprakfun videos. they cover most of what the LT videos cover but in a different interpretation. Both worth watching.
• http://web.archive.org/web/20020909153731/http://www.macs.ee.mcgill.ca/~roberts/SPICE/Welcome1.html - I have come across this book in my used book store browsing, and own a copy of the 2nd edition.

General Notes

0 is a gnd in the netlist. that means you can go to: view - spice netlist, and the path items will be 0 V001 or some variation thereof. the netlists are text files, and easily readable.

Simulating a delay

https://www.youtube.com/watch?v=-aQ77YI7inI A competent user of LTSpice. A good video to show usage and a reasonable circuit as well (the circuit is essentially simulating a 555 timer from discrete (well op amps) components).

Guaranteed to Work on Linux (TM)

For 32 bit linux, use LTSpice XVII (which I have running on Devuan/Debian 12).

Stepping Parameters

beginning, end, interval. E.g. test a capacitor from 2nf to 10nf in 2nf steps.
