others


Hello all

We have a partially-routed board, with some very carefully hand-routed
traces and some other routed lower-speed lines.

We wish to try autorouting the rest (with constraints thrown in, of
course), but protecting the most critical lines.

I believe Specctra, by default, protects all previously-routed wires.
What do I write in the .do file to tell it it's OK to rip up and
re-route some wires?

Cheers,
Richard
