Just a short note of caution ....

This problem can be avoided if you turn off that new "-register_duplication" feature.

a nice "feature" !! you should call thise feature "force core dump" then people would know to avoid it, and not spend hours of frustration!

Bret,

Before sp1, "-register_duplication" helped me meet timing when IO buffer registers needed to be duplicated. Do you know of another work around ?

Hi Rudi,

We've seen one similar case and that was a Windows only failure. If you have access to a Linux or Solaris machine, that might work. On the other hand, that case wasn't an SP1 regression like yours is, so they may be different problems. If that doesn't work, a webcase would be the next suggestion.

Bret,

the reported problem occurred on a Linux system. We only use a windows notebook for downloading of bit streams and ChipScope, otherwise only Linux.
