Preservation level: Final leads to Quartus crash on re-run

Hi Alex,

For the stacked logic lock regions, I cannot comment on this. It really depends on your design.

I'm sorry but I cannot help you unless you give me your design, because I cannot replicate the error and I don't have a design to give to the engineering team.

Usually IE messages require engineering team's help to solve as they are able to make checks on atom level and some internal checks, hence find the root cause.

Are you able to replicate this error on a smaller project?

Regards,

Nurina
