Getting started

Setup tools on linux or mac (or WSL on Windows)

For the analog toolchain we need some tools, and a process design kit (PDK).

• Skywater 130nm PDK. I use open_pdks to install the PDK
• Magic VLSI for layout
• ngspice for simulation
• netgen for LVS
• xschem
• python > 3.10

Clone the github repo

git clone git@github.com:wulffern/aicex.git
git submodule init
git submodule update

You need to add the following to your ~/.bashrc

export PDK_ROOT=/opt/pdk/share/pdk
export LD_LIBRARY_PATH=/opt/eda/lib
export PATH=/opt/eda/bin:$HOME/.local/bin:$PATH

Make sure you load the settings before you proceed

source ~/.bashrc

cd aicex/tests/
make requirements
make tt
make eda_compile
sudo make eda_install
sudo python3 -m pip install matplotlib numpy click svgwrite pyyaml pandas tabulate wheel setuptools tikzplotlib
source install_open_pdk.sh
cd ../..

Install cicconf

cd aicex/ip/cicconf
python3 -m pip install --user -e .
cd ../..

Install cicsim

cd aicex/ip/cicsim
python3 -m pip install --user -e .
cd ../..

Check that magic and xschem works

To check that magic and xschem works

cd ip/sun_sar9b_sky130nm/work 
magic ../design/SUN_SAR9B_SKY130NM/SUNSAR_SAR9B_CV.mag &
xschem -b ../design/SUN_SAR9B_SKY130NM/SUNSAR_SAR9B_CV.sch &
