DRC Fixing in Encounter

metalhead

 Hello

Ive been trying to do some DRC fixing in Cadence Ecounter. The basic problem I am facing is offgrid/nogrid routing errors. I tried setting the routeOngrid option true and routed the design again. But still there is no significant reduction in the number of errors. The total number of DRC errors is in the range of 1 million plus of which 900,000 odd are nogrid violations and 100,000 odd are offgrid. Can anyone please tell me about things I could do in routing by which I can fix these errors? Is routing/incremental routing the only way to fix DRC errors in Encounter? Any suggestions/replies are appreciated

    verifyTracks & generateTracks

    Until you can get verifyTracks relatively clean nanoRoute is going to give you nothing but grief.
    generateTracks is a good place to start, it will redefine your routing grid from scratch.
    To visualize whats really going on use the gui and turn on the tracks. walk through the individual routing layers.
    setLayerPreference trialTrack -isVisible 1

    If things  are still not lining up check your lef and follow the guidelines under .
