Net Widths
Explanation of Quilter’s Net Width constraint, detailing careful usage guidelines, potential conflicts with automatic constraints, and instructions for specifying custom widths.
Net Widths
In general, Quilter's development philosophy is to understand your design at the Physics Constraints level so that design parameters, such as Net Widths, can be independently managed on a constraint-by-constraint basis by Quilter, as opposed to using traditional design rules that can be overly conservative and cumbersome to define.
That said, Quilter supports a "Net Widths" constraint that can be used to specify specific trace widths for individual nets and net classes within your design.
If you want to assert custom Fabrication rules for your design, we recommend waiting until our support for custom stack-ups and design rules is complete.
Use Net Widths Carefully We don't recommend using the "Net Widths" constraint for global enforcement of fabrication rules. Net widths can "collide" with other physics constraints that automatically manage net widths and spacing, including High Current Nets. We recommend using this constraint sparingly.
How to specify
To specify a preserved pour, add the specific net or net class to the "Net Widths" constraint during Circuit Comprehension by clicking the Add, Add multiple, or Add by netclass buttons beneath the table.
