Then, in the General Properties section, we already have voltages set for some of the nets (see image below). Setting voltages helps assist circuit simulation for impedance drops and signal integrity analysis. The remaining worksheets, such as Component > Component Properties > General and Component > Pin Properties > General, are not set. This concludes the schematic side of the constraint manager and its use. Now we will push these constraints to the PCB layout side to maintain project integrity. After that, we will simply review the constraints found in the PCB layout for our demo board. f Within the Constraint Manager worksheet, Create a Constraint Set that you will apply later. f Apply that Constraint Set to a class, group or region in your design. f Repeat similar steps for all kinds of constraints (Physical, Electrical, Spacing, Manufacturing and so on). 23 www.cadence.com OrCAD X Constraint Management Guide
