Why do you need to match in Quartus? If DSE is producing a result that works for you, can't you just use that generated project?

We version control our project, but only at the source file level because the netlists are simply too huge (several GB) to be in a git repo. Couple that with an internal need for reproducibility (assuming same version of same Quartus toolset), we need to have a single project that can be stored rather than having multiple DSE generated projects.

While yes I could set DSE running again to get the required result, that takes a day to run and find the working seed (densely packed Arria 10 SX660). I'd rather then just be able to store and compile that one seed in Quartus the future (~4hrs) if I need to reproduce the netlist.

But anyway, it's moot now, I found the issue to be that I'd added the processor limit to the Quartus file after DSE generated its archive, so the two weren't running on the same `NUM_PARALLEL_PROCESSORS` setting.
