cicsim 0.1.2

Custom IC Creator Simulation Tools

Custom IC Creator Simulation Tools

Caution

If you're looking for the cicsim that controlled spectre, then look in the cadence branch. From 2022-10-14 I decided to go all in on open source tools like ngspice, and thus discontinued support for spectre

Why

This is a script package I use to control ngspice, it can

• Run corner simulations
• Create IPs (used in wulffern/aicex)
• Create simulation directories

Changelog

Version	Status	Comment

Know what python you're running

Python is great, however, python exists in many different versions, and you can never trust that the right version is installed on the system that you're going to use. As such, always know what you're running.

Option 1: Build yourself

If you don't control the system, then you can still install locally https://randomwalk.in/python/2019/10/27/Install-Python-copy.html

It's not straightforward though, and it can be a rabbit hole that takes some time

Option 2: Check version

Try

python3 --version

Or

python --version

Option 3: Set version

Sometimes multiple versions can be installed, if so, then you can add the following lines to your .bashrc file

alias python3='/usr/local/bin/python3.8' alias pip3='/usr/local/bin/pip3.8'
