Autorouter - Mixing trace widths for same net..
39 1

Autorouter question. I have a trace that needs to be wide because it is prt of the power grid. All of my default traces will be 11 mil in width, but this particular trace will be 35 mil in width. One of the devices that is being connected to teh power grid has a pad width of only 11 mil, so routing a 35 mil trace won't work since it crashes into the pads next to iit, and autorouting can not complete. When the traces have the same NET name, is there a way to designate a specific segment to have a different trace width than the rest of the segments? The only option that I can find now is to let the Autorouter fail, and then manually connect the problem segment, but it would be nice to be able to designate specific segments oif the same net to have different trace widths.

I don't think you can get the autorouter to route with a variable trace width. Your best option would be to route the segment from the pad to the wider trace by hand and then run the autorouter. Even so you may have to manually route all the tracks of this type and then tell the autorouter to leave them alone while it does the rest of the routing.
