No—Quilter automatically detects and extracts key physics constraints directly from your schematic. It identifies constraints such as impedance-controlled signals, differential pairs, length matching, high-current nets, and sensitive circuits through its Circuit Comprehension interface.
After Quilter extracts these constraints, you review and verify them for accuracy. You can manually adjust or add additional constraints if needed, ensuring the layout meets your precise design requirements.
For more information on the signals Quilter uses to automatically identify physics constraints in your design, see our documentation.
