2.7.2.1. Wildcard Characters

To apply constraints to many nodes in a design, use the “*” and “?” wildcard characters. The “*” wildcard character matches any string; the “?” wildcard character matches any single character.

If you apply a constraint to node reg*, the Timing Analyzer searches for and applies the constraint to all design nodes that match the prefix reg with any number of following characters, such as reg, reg1, reg[2], regbank, and reg12bank.

If you apply a constraint to a node specified as reg?, the Timing Analyzer searches and applies the constraint to all design nodes that match the prefix reg and any single character following; for example, reg1, rega, and reg4.
