priority [net_name ...]
where net_name is the name of any net in the design space.
The priority command allows specific nets to be marked by the router as "critical", and always put at the front of the list to be routed before any other routes. Qrouter does not itself mark any routes as critical, but instead prioritizes all nets according to its ordering algorithm. Prioritized routes are more likely to follow the ideal route solution, as there are no other routed nets in the way. Multiple nets may be specified at the same time, in which case they are prioritized in the same order as given on the command line. If the priority command is issued multiple times, nets given in later commands will have priority over nets given in earlier commands.
priority is implemented as a built-in command in qrouter, only in the Tcl version.
