No easy to undel that in Encounter...Originally posted in cdnusers.org by bougantp
One possible workAround is to:
1- Setup your restrictive dontUse list
2- Run a full block optimization
3- set a dontTouch on your specific module
4- relax your dontUse list
5- run incremental optimization
For the step 2, you might have to specify a path_group (Someting available in 71), if your critical path is outside your special module, to force encounter to work for path within it.
