Routing Parameters

Overview of Routing Parameters available within Quilter

Quilter is a fully automated, end-to-end designer that is capable of both placement and routing.

Routing Parameters help you influence and control how Quilter implements your board's netlist, to ensure that the layout candidates Quilter generates meet all of your electrical requirements and preferences.

More specifically, routing parameters can be used to:

1. Define a custom stack-up that includes power planes dedicated to specific nets within your design (coming soon)

2. Assert custom net widths for specific nets or net classes to override or supplement the Fabrication rulesfor a particular layout job

3. Lock routing strategies during iteration, so you can "save your work" throughout the design process

Parameter	Description	Preference	Requirement
Pre-routed traces	Lock the routing path of sensitive signals.	❌ Pre-routed traces are always preserved	✅ Leave within board outline in input file
Preserved pours	Preserve existing copper pours from your input pile for Quilter to use when generating candidates.	❌ Preserved pours are always respected	✅ "Lock" pours you want to preserve in input ful
Keepouts	Prevent Quilter from routing traces through specific geometric areas within your design.	❌ Keepouts are always respected	✅ Add keepout to your input file
Net Widths	Manually specify net widths for individual nets or net classes in your design.	❌ Net widths are always respected	✅ Specify "Net Width" in during job setup
