Never fails that when I make the accidental mistake of moving a part around
a board on anything less than .05" grid, the autorouter will never finish
the job again. If I drop the routing grid to 1mil, it could take 12 hours
In cases where I place the parts on a grid of .05, it is usually a fast
route, with only slight mods needed if there is a traffic jam.
But, like yesterday, on a board layout I have been working on for weeks, I
dropped the grid to .0125 to move some parts closer together, then remained
in that grid to move some other parts, sure enough, typical route is 20
minutes plus, and never completes using 10mil, less than 10 mil I am
looking at hours to route.
The only solution to complete the board is to start over, new board, place
everything .05", route at 10 mil. Major hassle as there are tons of parts
placed in specific locations.
If there were a workaround for this nightmare I would appreciate it.
