pyseim 0.1.1

Waveform viewer and analyzer for ngspice/kicad

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

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.
