CADSTAR Constraint Browser

Fast, efficient constraint definition for design engineers

CADSTAR Constraint Browser provides a fast and effective way for Design Engineers to enter even the most complex rules and net constraints, using a straightforward spreadsheet style interface, linked to both Schematic and PCB Layout.

The Constraint Browser works alongside your Schematic design so you can cross-probe selections to quickly locate nets. Constraint information is stored in a database that is shared with PCB Layout, Routing and Analysis, providing a smooth exchange of data and a consistent user interface across all applications in the high-speed design flow.

Focus on the core design flow by grouping critical nets into groups such as DDR3 or PCI Express data channels, then constrain them by assigning differential pairs, controlled impedance groups, sequential skew groups and more...
