Minimum Delay Requirement timing assignment


Specifies the minimum acceptable point-to-point delay, that is, the time required for a signal from an input pin or register to propagate through combinatorial logic and appear at an output pin or register. This assignment does not influence timing-driven compilation. The following table lists the legal assignment types and the path(s) affected by each assignment:

Assignment Type/Location Affected Path(s)

Point-to-point assignment from register to register.

Point-to-point assignment from input or bidirectional pin to register.

Point-to-point assignment from register to output or bidirectional pin.

All paths originating from the source node and feeding the destination node.
