Multiple uses of core partition
- 4 years ago
Hi,
Yes, @sstrell is right. If you want to import the design partition and reuse it multiple times, you would need to choose the synthesized snapshot.
Because the final snapshot preserves placement and routing (can be assigned to only one design partition) while the synthesized snapshot does not have physical preservation (can be assigned to more than one design partition).
You may check out the documentation for the difference of partition snapshot:
Thanks.

Thanks for replies.
Editing .qsf file solves the adding multiple partitions. But Quartus gives me an error:
" The Partition Database File "../**_final.qdb" implements a partition that was preserved at the "final" snapshot and is assigned to 4 design partitions. Only Partition Database Files preserved at the "synthesized" snapshot can be imported into more than one design partition. "
My goal is decreasing the Compilation (mostly Fitter) time but do "synthesized" snapshots help in this situation? I expected a "final" snapshot can be used multiple times. I wish Fitter can replace the final snapshots in the device map.

You can't use a final snapshot because then all the copies would be placed in the exact location right on top of each other which obviously can't work. You have to use the synthesized snapshot so each copy can be placed in its own unique location.
