00 - Constraint Manager with OrCAD X Capture

A constraint is a user-defined requirement applied to a net or pin-pair in a design. Electrical constraints (ECS) govern the electrical behavior of a net or a pin-pair in a design. For example, you can capture a constraint to define the propagation delay and relative propagation delay for a driver-receiver pin-pair in your design.

To capture constraints, Cadence provides a tool named Constraint Manager. You can use Constraint Manager with OrCAD X Capture (referred to as Capture elsewhere) to define and manage electrical constraints as you implement the logic.

Depending upon the license used for Capture, the Constraint manager provides different levels of functionality for managing constraints.
