Creepage between traces on a PCB surface Cadence OrCAD X Presto PCB Editor does not support creepage and clearance rules, but Allegro X does. However, you can at least set a spacing rule to control your creepage if you don't have coatings on the PCB. Notice how it addresses spacing in this image below. We cannot distinguish between clearance or creepage with this constraint, because coatings are not taken into account. Therefore, this distance could be the distance midway between the creepage distance and the clearance distance, thus giving an average clearance, which could in effect violate the creepage, clearance or both. Hence, if you do use this as a substitute for creepage or clearance, consider using creepage and only when a coating is not present. If a coating is present and you still use this constraint in OrCAD X, at least increase the distance more than usual with an acceptable tolerance to address both your creepage and clearance needs. However, using Allegro X is recommended at this stage. 13 www.cadence.com OrCAD X Constraint Management Guide
