I have already compiled a large design and wrote out .ddc. and exited DC. I am looking to do some optimizations on the same design. If I load that .ddc, I get different QoR than the original. I am just loading the .ddc. What am I doing wrong? Is there any other file I should load?

Shouldn't the constraints be contained within the ddc? I think most are. But it's possible that the timing_derate contraints are not contained in the ddc. If anyone can confirm this please comment. I'm running experiments now.
