This is a repository that contains links to other github repositories with analog designs. Most of the designs have been developed as part of the NTNU course TFE4188 - Advanced Integrated Circuits.

ci/       # Continous integration. Mostly check of the tutorials
docker/   # Dockerfiles to create a container with the tools
ip/       # all the IPs, config.yaml contains the links
tests/    # Makefile used for installation of the tools

Installing, and usage

For a detailed scription of installing the tools, see http://analogicus.com/aic2026/the_tools

For a description of the usage, see https://analogicus.com/aic2026/sky130nm_tutorial

For the impatient

git clone --recursive https://github.com/wulffern/aicex.git
python3 -m pip install cicconf
cd aicex/ip
cicconf clone --https
cd ..

I assume you have docker installed, or have windows subsystem for linux.

⚠ It’s a very good idea to check what’s inside scripts before you run them

./run.sh

You should now see a cyan “aicex@~$” terminal.

Check that you can open a new X terminal

xterm &

You should now be able to run the tutorial at https://analogicus.com/aic2026/sky130nm_tutorial

Known issues

Xschem

Netlisting seems to be done not by pin number, but by order of B’s in .sym. Also, I’ve experienced different ordering for subckts, and for top cell
Be careful of x1[5:0] notation. Xschem does not automatically discover if there is another same x. I would recommend always uniquely naming instances with bus notation

docker

Using SSH: The aicex user has a uid of 1001, however, if you try and run it on a machine with a different uid for your user, then it does not seem to work.
