Review and edit constraints

An overview of Quilter’s Constraints step, outlining how to define and validate physics constraints for your PCB layout.

Computed Constraints

Differential Pairs

Based on the parameters from your stackup, Quilter uses Simbeor to calculate the correct trace width on each layer. Currently the frequency is assumed to be 1 GHz.

Power Nets

For each net and current you defined on the previous Comprehensions page, Quilter calculates the appropriate trace width to limit temperature rise to 20*C, using the IPC-2221 definitions.
