Quilter can now automatically place bypass capacitors
And every placement on every layout is validated with automated Physics Rule Checks (PRCs)
At Quilter, our mission is to help companies ship better PCBs faster by automating the tedious, time-consuming tasks that slow down product development.
And when it comes to digital electronics design, few tasks are as painstaking as placing dozens or even hundreds of bypass capacitors to ensure proper decoupling.
Nearly 50 years after the invention of the first autorouter, designers are still placing bypass capacitors by hand. No longer!
We’re pleased to announce a small but mighty EDA industry first:
Quilter can now automatically detect, associate, and place bypass capacitors in new layout jobs, validating every placement decision using our new Physics Rule Checks framework.
Say goodbye to manual capacitor placement and hello to faster, more reliable designs.
How it works
1/ Quilter automatically finds bypass caps
After uploading your input files, Quilter automatically detects bypass capacitors and determines which components and pins need decoupling.
2/ Submit your layout job
Quilter optimizes placement for all identified bypass caps. Even in this first release, our algorithm will:
- Strategically place smaller capacitors near high-current voltage sinks to minimize impedance and stabilize power delivery, preventing voltage drops.
- Identify and optimize 1:many bypass capacitor relationships between ICs and their capacitor banks to ensure distributed decoupling across frequencies.
- Minimize overall power delivery impedance by reducing trace length and via count, lowering parasitic effects in the decoupling network.
3/ Review layouts and physics rule checks
Each candidate layout includes Physics Rule Checks (PRCs) for every bypass capacitor, verifying proper placement near assigned pins and minimal via usage.
Try it for yourself!
Haven't tried Quilter in a while? Now is the perfect time to submit another design. We've made several exciting improvements in recent months:
- Added a new Physics Rule Checks (PRCs) framework to validate the functionality of Quilter-generated layouts
- Added support for impedance-controlled signals (differential, single-ended) and bypass capacitors
- Made layout jobs another 10x faster
