   '-CONGEST--=--min,max-'   

Indicates whether congestion is allowed for each node row.

CONGEST allows you to indicate the weighting preference for uncongested nodes, or to disallow the use of congested nodes.

A range of LOW,LOW indicates only uncongested nodes are allowed for the node row. A range of LOW,HIGH indicates uncongested and congested nodes are allowed for the node row.

min=LOW or HIGH and max=LOW or HIGH. The minimum default is LOW for all node rows. The maximum default depends on the node being defined:
