Topological (rubberband) router for printed circuit boards. (work in progress)
After the last development update, NLnet granted us additional 10 000 EUR for new tasks. For this money, we have implemented some experimental features, which are covered in the below sections.
Meanwhile, we are also working hard to complete all the unfinished features and fix as many bugs as possible to release Topola v0.1, the first alpha version of the Topola PCB router, which we hope to accomplish by the end of this year.

For the past (almost) 6 months, Ellen Emilia Anna Zscheile (@fogti) worked on developing a new routing backend for Topola that uses a much smaller navigation mesh than currently.

December 2024 Development Update
Squeezing through under bends, security audit, accessibility testing.
This is the last development update for the Topola PCB router in this year. We now have successfully completed all the tasks funded from the NGI0 Entrust fund and went through a security audit and accessibility testing mandated by our participation in the fund’s programme.

October–November 2024 Development Update
Web demo, new logo, EasyEDA Specctra DSN/SES import/export, contracts-try Rust crate, GUI improvements
Just like in the previous update, we have spent the last two months on infrastructure tasks and smaller features for the Topola PCB router. Most notably, we have now have an online Web demo and a new logo.

August–September 2024 Development Update
We have spent the time since the last update on infrastructure tasks and smaller features.
Most importantly, we have configured Codeberg Translate, the Codeberg’s (@Codeberg) instance of Weblate, for Topola. This provides an easy way to translate Topola without having to know how to use advanced software such as Git.
We invite you to translate Topola to your language too!
