How to Quickly Determine Schematic Differences

Identifying and tracking schematic modifications throughout the design process can be difficult, especially with multiple engineers working on the same project. Instead of wasting crucial hours scanning through the entire schematic to determine what changed, designers should spend their time focused on design creation. With OrCAD Engineering Data Management (EDM), differences between schematic revisions are automatically identified and reported graphically, improving collaboration and expediting schematic creation.

This how-to will provide step-by-step instructions for comparing versions of a schematic with the Design Compare functionality in OrCAD EDM.
