Abstract
According to an aspect, a plurality of nets are grouped into a plurality of buckets based on timing criticalities associated with the nets, and different TCRs are assigned to each of the buckets. For each of the nets, a TCR for the net is determined based on the TCR assigned to the bucket containing the net. Global routing of the net is performed according to the TCR and to one or more constraints associated with the net. The TCR for the net is incremented by a specified amount in response to the global routing of the net resulting in violating at least one of the one or more constraints associated with the net and to a stopping criteria not being met. The performing global routing and incrementing the TCR for the net is repeated.
