Which Quartus version are you using? Could you try using the latest Quartus version to check if the issue persists?


For reference, the KDB article below outlines the factors required to achieve identical results across compilations:

Additionally, I recommend using incremental compilation to preserve placement and routing results for specific portions of your design:

    We are using Quartus Prime Lite edition 18.1.1 Build 646 with patch 1.01. This version is required for implementing Intel PFR. We can try with pro version - that's the only option left. Since our code is almost finalized, implementing incremental compilation will be quite difficult at this stage as it calls for changes in code structure itself I believe. In the first link shared, it is mentioned "Even changes in comments" can result in different results.

    Let us know if there is any other workaround.
