PCB Design Constraints Manager

Your constraints defined within your Schematic are carried through to PCB design


Meet your electrical performance criteria by setting design constraints. Apply constraints to parts, pins, electrical nets (E-nets), differential pairs and other objects in the Constraint Browser.


Constraints may be set and modified in either Schematic or PCB Editor, and annotated forward or backward between designs, ensuring they are always in sync. You enter constraints in a clearly-presented object hierarchy, in clear tables. Define classes and groups to organize your design quickly, create differential or pin pairs and buses. Cross probe your selection between the canvas and constraint browser at a pin, part, net or E-net level, in both Schematic and PCB editor simultaneously.

You can constrain signals at E-net or Net level. These may be high-speed or more basic constraints. Improve your canvas visibility by applying constraint colors to specific objects, with additional visibility options such as shading between differential +/- pin pairs and E-net pin pairs. Constraints are reflected in features such as the routing balloon that displays measured values against constraints in real time.

Maybe you want to add constraints in the schematic, where you can see what the circuit is doing. Maybe you want to do that during PCB design – selecting items to constrain in physical layout or cross-probing them from schematic. Whatever you prefer, eCADSTAR works with you. Constraint Browser is built into both eCADSTAR Schematic Editor and eCADSTAR PCB Editor
