Week 12 of my Google Summer of Code journey with CircuitVerse (August 10th to August 16th) was a really fun mix of something personal and a lot of progress on the project.
👕 The Most Awaited Package!
At the start of the week, something I had been waiting for finally arrived — my CircuitVerse T-shirt! 🎉
If you guys have been following my blogs, you might remember that my team won CircuitVerse's MERGATHONE Repository Cleanup Contest at the end of May. I wrote about it in my Week 1 blog.
When I opened the package and saw the CircuitVerse logo, it honestly felt amazing.
It might just look like a T-shirt, but for me it was a small reminder of where I started — using CircuitVerse as a student for my digital logic course, then contributing to it, and now spending my summer working on it through GSoC. 🩵
🧪 Finally Fixing the Round-Trip Gaps
Coming back to the technical work, I followed up on all the problems the Editor's Picks tests had exposed last week.
The main fixes were around:
- 🔌 Preserving complete wire topology, including dangling, standalone and multi-port nets.
- 📐 Preserving routing, intermediate nodes, component port positions and other layout details.
- 🗂️ Restoring important project state like the project name, clock settings, focused circuit, tab order and annotations.
After working through these issues, all 12 Editor's Picks projects were finally passing the complete round-trip tests! 🎉
I raised PR #1194 with the fixes and the new test coverage.
The PR is still under review, so there may still be a few edge cases to clean up before it gets merged.
🔄 Starting the Auto Layout Feature
I wasted no time and moved on to the next part of my GSoC project — Auto Layout using ELK.js.
This was actually a feature my mentors and I had discussed way back during the Community Bonding period. The idea is simple: when a canonical circuit does not already have component positions, the importer should still be able to generate a clean and readable layout automatically.
ELK.js brings the Eclipse Layout Kernel's graph-layout algorithms to JavaScript, letting us automatically calculate clean positions for connected nodes and edges. That makes it a really good fit for laying out circuits when position data is missing.
I had already spent some time researching ELK.js earlier in the summer, so starting the implementation after finishing the canonical pipeline was not too difficult.
It is also a pretty interesting feature to work on because now the problem is not just about preserving circuit data — it is also about deciding where everything should actually appear on the canvas.
🔮 What's Next
Next week, I want to get PR #1194 through review and merged, addressing any mentor feedback or edge cases that come up.
Alongside that, I'll finish the Auto Layout feature and raise a PR for it.
Really looking forward to next week! ⚡💻
