Trace lock and re-optimization

e14 Contributor

It would be nice to be able to lock traces the way components are

locked. This would allow experimenting with routing on one part of the

board, issuing a global 'ripup' command, without worrying about ripping

up existing traces.

 

If this feature is implemented it would also allow for another feature

I've always wanted: re-optimization. Imagine running Autoroute but

without the routing pass. That is, only the optimization passes are run.

This would be very helpful to clean up a manual routing job.

 

In re-optimization, any trace that is not locked is fair game for the

autorouter to re-route according to existing costs (without changing the

connectivity). Of course, locked traces remain untouched.

    I agree Andrew, this could be useful.  Even if just to protect a highly

    optimised section of the layout (like a power supply for instance).
