Manage Constraints

A simple way to define a constraint is to consider it as an objective that can be used to influence the possible implementation, placement, or routing in a system. Constraints are therefore requirements that need to be followed during design implementation.

By understanding constraints in your design hierarchy, you can determine specification limits for design objects.

A constraint can have parameters that are pre-defined name-value pairs that further define the design intent and the status of that constraint.

You can manage the routing constraints using Virtuoso Routing Constraint Manager.
