Bypass Capacitors

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.

Here's 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.
