    Works great.  Have done many boards that I have only routed the

    critical  traces.  The trick is to insure that you modify the line in

    the ulp to convert to dsn

     

    int preprotect = 1;

     

    This will insure that if you preroute some traces they will be  left

    alone.     Just let it finish because the final passes are to

    optimize.   Have done about 20 boards and have had great luck with

    some really tough routing problems.

    Seems to be a very nice product.

    Is there a way to select only the bottom layer for routing?

     

    Jesse

    Yes, certainly. Simply deselect the top layer in Freeroute. I have used

    it for many small single sided boards. I usually make a few test runs

    and then move the components in Eagle so that tight spots disappear. The

    'push and shove' manual routing works great as well. If the autorouter

    does not manage, just delete a few routes, draw some connections by

    hand, and start the autorouter again. No need to route 'nicely' by hand,

    the autorouter cleanup phase takes care of that.
