Using the Virtuoso autorouter: routing grid

RVERP

How do I set the routing grid? I can use the option to route on the routing grid, but I can't find how to check it's value, or how to set a new value.

I want to force the autoroute to place spines/vias on the exact grid I want, so I suppose the routing grid is what I have to use.

    Alright, the router is behaving als expected. The problem was that I only had set a default routing grid. When I added metal specific routing pitches, all was fine.

    Probably there are values for this in my tech file, and they were overruling the default (logically).

    The only thing I don't get is that manual wire editing behaved according the default values, while automated routing behaved according the metal specific values.
