kicad-nikfemm's Introduction

what is this?

This kicad plugin uses nikfemm simulator to plot power density and voltage on PCB geometries.
Please note that this is just a demo and I tested it on linux systems only (but you could manage to make it work on windows quite easily).
Also you'll need to install all the dependencies by yourself.
P.S. nikfemm can simulate infinite many layers but for simplicity this plugin simulates two layers with hardcoded thickness of 35um

installation

to install the nikfemm python module:

git clone https://github.com/nikisalli/nikfemm.git
cd nikfemm/python
pip install . (you'll need cmake, make and a compiler installed on your system to build the wheel)

to install the dependencies for the plugin

git clone https://github.com/nikisalli/Kicad-nikfemm
cd Kicad-nikfemm
pip install -r requirements.txt

to install the plugin:

go to the kicad plugin manager
click the install from file button
select the zip in the main folder of this repo

BOARD_ITEM_CONTAINER object has no attribute 'GetReference'

Steps to repeat

When I click the icon 'FEM', error dialog (shown as attached) pop up and cannot continue.
I tried several PCB files, same error occurred.
My KiCad version is shown as follows:

Kicad crashes after clicking start simulation

Hi, I used the same settings as you provided in the example video lol.mp4
Kicad is crashing after initiating the start simulation.
Should the minimum and maximum voltages in the net should always be set? for example for a 12V net, should we select a component for 12V and 0V?
