Use this constraint to reset a net's criticality to its default value, which is 5.
Net criticality is a guide for the place-and-route tool to keep instances connected to a net as close as possible, at the cost of other (less critical) nets. Net criticality can vary from 1 to 10 with 1 being the least critical and 10 being the most.
You can use one or more of the following commands or GUI tools to reset net criticality:
