Short Violations in Encounter

iopad

After doing placement and trial route in Encounter, I get over 1000 "short violations". The violations are all concentrated within the small left corner of my design. The violations are between wire/wire, via/wire, via/blockage etc. Strangely I don't get congestion markers in the left corner. The shorts are all on metal layers M1 and M2. What should be the starting point in resolving this problem?

SHORT: Regular Via of Net DP_OP_8555J1_629_6502_n22 & Pin of Cell DP_OP_8555J1_629_6502_U39  ( M1 )
Bounds : ( 53.930, 72.240 ) ( 54.040, 72.265 )

  • I think you should find out why nanoRoute is having so much trouble. Sounds like it could be a floorplan issue, but it's possible that if nanoroute is allowed to continue, it will clean things up eventually. In any case, you should run nanoroute with setNanoRouteMode -drouteAutoStop false, so that it will keep going and then you'll have a route (with violations) to look at and diagnose the problem.
