M1.3/M1.4 PAR: The signal "GLOBAL_LOGIC0" is not completely routed--messages about unrouted nets that are not in the input design

説明


General Description:

PAR may issue a message about unrouted nets named "GLOBAL_LOGIC0" or

"GLOBAL_LOGIC1". These are the re-named power and ground nets from the

input design. The design is not completed until all connections

including these have been routed.

ソリューション


In some cases, if the message looks something like this:



//////////////////////////////////////////////////////////////



Dumping design to file "drink_top_r.ncd".

Total CPU time 22 secs

Total REAL time: 2 mins 41 secs

End of route. 169 routed (97.69%); 0 unrouted active,

4 unrouted pwr/gnd.

No errors found.

The signal "GLOBAL_LOGIC0" is not completely routed.

WARNING:baspw:130 - Design is not completely routed.



//////////////////////////////////////////////////////////////





If you get this warning, the design is not complete. You

should run Re-entrant Routing and to try and get the net

to route. If that does not work, try a different cost table

and re-run the design.
