It has been a year since I had last time touching the code of my test wafer generator, and I was hoping that others might keep maintaining my code and keep it up to date, but instead folks just walked away after the first minor dependency changes.
The idea of DanubeRiver is to call all the generator functions from LibrePDK and generating test structures for characterizing any given process.
The original code can be found on my GitLab repository here:
https://gitlab.libresilicon.com/generator-tools/danube-river
The output rendering for GF180MCU, which can be found in tapeout/gf180.gds is shown below.
However, in the meanwhile, lots of code in gdsfactory has changed and after several days of intensive hacking I finally got LibrePDK and Danube River to finally spit out a GDS file at all containing structures which at least kind of resemble the original test structures, as can be shown below, but it’s still kind of out of wack.
I keep on working on Danube River and LibrePDK in the next few days and try bringing it up to speed, fixing all the bugs currently still present.
I’ll be doing so in the refactor branches of LibrePDK and Danube River and will merge them into master after some rebasing.
Those are the repos, I still need to update the documentation on the Wiki page for addressing some changes when it comes to installation of the tool.

Problem,s yet to be solved
- Interconnect: The routing has changed
- Area of capacitor electrodes needs a slight rework
- Spacing around the transistor structures is broken
