31. Give it a name in the PhysicalCSet field (e.g. BGA-REGION-PCS, for Physical Constraint Set to distinguish it from the spacing rules we will create for the BGA Region). 32. Click Ok. The window will disappear. The Physical CSet you created will appear (see below). 33. The final step is to apply this BGA-REGION-PCS Constraint set to our newly created Physical Region (BGA-REGION). 34. Go back to the Physical - Region - All Layers Worksheet (see below). 35. In the image above, notice the Referenced Physical CSet column to the right of the 'BGA-REGION' field. Click that cell and select the Physical CSet we just created, BGA-REGION-PCS. 36. Now we have our physical rules applied to the Physical region! Notice that the widths of the Conductor row are already 0.100 mm, which is lower than our 4 mil minimum requirement for conductor trace width in this region. That is a satisfactory value, so let's set the spacing rules for the BGA region by again, first creating the region (but in the Spacing domain). Then we'll create a Constraint set specifically for that region and finally apply it. 20 www.cadence.com Part 1 of 5
