Steps:
1. Open the Constraint Manager.
2. Go to the worksheet shown below.
3. Left click and the Create DFFCopperFeatureCSet will appear.
4. Click Ok.
5. In the Line Width column, set the minimum to what your manufacturer can make within the allowed budget (4 mils, 0.102
mm).
Note: This manufacturing rule may seem redundant if we already set the trace width in the Physical Constraints section.
However, not all manufacturers have the same criteria. We want to be able to have our design without influence from the
manufacturer's capabilities. We also want a modular way to swap out manufacturers without having to change our original
design trace widths every time. Hence the 'redundancy'.
