autorouting and DRC's

stellar

  I see conflicts and DRC's after I autoroute.Is this normal mode or are there settings that will just leave a ratsnet connection with no tracks? Any tips and wisdom on the autorouter you can offer is greatly appreciated. I tried the Smartroute and think it does a better job of getting close to 100%. I'm almost finished with my first board and have 5 conflicts to clear up and will be ready to order the board so thanks for all the prompt/knowlegable advice. I'm fanning out power and gnd first. If I disable fanout and power and ground before autorouting the rest will those vias and tracks remain frozen in place or will the router move them if required? Probably it moves them unless I lock them in the constraints. It appears that if I leave fanout on while autorouting all nets together I get a lot of vias for the power and ground connects so routing separate is the best it appears and is the way I'm accustomed to doing it in Layout.

    One once told me a completed board with some drc's are much better than a non completed flawfree board. Spectra tryes to do the board and demands some cleanups, and demands a review to remove drc's.

     

    It is always a good commen sence to fanout first. It is just so difficult to place and route a cap in a QDDR area on a nano board :-).

    Yes I'm liking this much more than Layout which didn't attempt to complete a route if there were conflicts. I see you can enable ripup etch if it conflicts but I'm finding that the manual router works so well it doesn't take long to cleanup conflicts.
