Quilter's objective is to limit the type of manual configuration of design rules that are typically required when setting up legacy design automation tools like autorouters.
Instead, Quilter attempts to automatically derive design rules for each of the candidates that it explores from two key sources:
Your schematic
Quilter automatically analyzes your schematic to identify critical signals, such as impedance-controlled lines, differential pairs, and high-current nets. You review and verify these to ensure Quilter accurately captures your intent.
When generating your layout candidates, Quilter automatically completes the necessary physics calculations to create the design rules for each stack-up it produces, and performs both DRCs and PRCs (Physics Rule Checks) to confirm that the implementation complies with fabrication and physics requirements.
Manufacturing constraints:
Quilter maintains pre-validated stack-ups and fabrication rules from various manufacturers that include trace thicknesses, clearances, and minimum distances. If your preferred manufacturer isn’t already supported, Quilter can incorporate their specific constraints into your profile.
This approach streamlines the layout process, reducing manual setup and ensuring each generated layout adheres to your requirements and manufacturing capabilities.
