Files and folders

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

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 &

python3 -m pip install cicconf cicspi cicsim
cd ip
cicconf clone --https

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

• The aicex user has a uid of 1000, however, if you try and run it on a machine with a different uid for your user, then it does not seem to work. Don't know how to fix it yet.

Ngspice

• In 44.2 there is a missing $LDFLAGS on the line shell g++ --shared $v_objs $v_lib -pthread -lpthread -o $soname to compile on my M4 mac
