Power Router Troubleshooting

If you have trouble connecting power structure objects, particularly if the objects are created externally, check the following:

• If you are running the power router on a power or ground net, is the signalType property for the net set to power or ground?
  By default, the power router will only operate on power and ground nets. If the net is not specified as power or ground, then you must either change the net’s signalType property value or use -power_only false with the power router Tcl commands to permit the power router to route signal nets.
• Are the power structure objects labeled properly so that they will be recognized by the power router?
  For example, proute_pin_to_trunk will not connect to a tap pin that is labeled as a tie-off. Use set_power_type to ensure that the objects are labeled properly so that they will be recognized by the power router.
• Do you have shapes on a power or ground net that are unassigned and are only physically connected to the net by overlap or abutment?
  If the unassigned objects are pins, the power router might report that no pains have been found for router. Run extract_net_connectivity on the net to resolve unassigned shapes.
