PyS(e)im

PyS(e)im is an open source waveform viewer. It is meant to play together with ngspice and kicad. With just one click you can netlist, simulate and show the simulation results in a window:

Make sure to include something like the following in your ngspice control section:

.probe alli
.control
	save all
    tran 100n 1m uic
    run
    write
.endc

When running ngspice it should create a rawspice.raw file

How to use?

PyS(e)im is available on pypi:

pip install pyseim
pyseim --help

Features

• Netlist, simulate and show results with just one click
• Equation support

Alpha Status

• Only transient simulations working currently
• All signals in one plot

It is a very simple script (currently just one file). However, I find it already quite useful.

Ideas

• Show SOA violations
• Support for AC simulations
• ...

Fun Fact

The package name is close to PySim that was already taken. PyS(e)im is a close match. Seim means 'viscous juice'. Therefore, the icon is a honeycomb.
