samenet spacing violations

Priyatham
After routing using the NanoRoute - when I run a verifyGeometry I get some samenet spacing violations - all on VIAs. When I run verifyGeometry with -allowDiffCellViols, all these violations are cleared. So someone advised that its probably not the routing that's causing the violations but the cell design. But those are the standard cells for First Encounter and I have no clue why they might be causing the problem. Any advise on this and how to resolve this issue would be a great help.

Thanks,

Priyatham.

  • Hi Priyatham, Can you run verifyGeometry before nanoroute? This should isolate the problem to whether the violations are coming due to routing. Also note that one of the rules for std cell design is that any cell should be able to abut any cell with legal orientation and not cause a DRC violation. Thanks
