Simulating Circuits in the CLI

My previous tutorial on EDA in FEL showed you how to simulate circuits using gspiceui with the gnucap simulator. This time I’ll show you to do the same using the command line interface (CLI) with the ngspice simulator. I had a few doubts regarding the use of ngspice and got them cleared in FEL mailing lists. We’ll not look at gnucap for now because I have to learn to use it myself. Alright so lets begin! 🙂

Prerequisites and References

These are the same as https://ashwith.wordpress.com/2010/09/10/circuit-simulation-in-gnulinux-lets-begin/

Do go through that tutorial first if you haven’t already.

In addition to this, you need to be familiar with SPICE netlists. Check the ngspice manual. It has a well explained, detailed description with a few examples in the end. To get started quickly go through this tutorial http://www.seas.upenn.edu/~jan/spice/spice.overview.html

I got some help with ngspice at the FEL mailing list as well. You can sign up here  https://admin.fedoraproject.org/mailman/listinfo/electronic-lab.
