A rebuild of our global routing submodule makes routing (another) 4x faster, now 27x faster since launch.

If you read our blog post from April, you may recall that Quilter is composed of 5 major submodules that handle placement, routing, and post-processing for all user-submitted layout jobs.

As a follow-up improvement to our first major router speedup in April, we’ve now also fully rebuilt our global route planning submodule, which is responsible for determining how major traces are organized and traverse the board space.

This second round of improvements meaningfully extends the already massive speed improvements we’ve unlocked since launch:

• Routing time has now improved from 6.7x → 27x faster since launch

• Total job time has now improved from 3.6x → 9.4x faster since launch

Most importantly, this means the typical successful Quilter job now explores 48 unique designs and produces 20 DRC-free, 100% complete candidates – all in less than an hour.
