Post-Fit Netlist Partition keeps using source file

Hi,

Should be caused by below. From the Intel® Quartus® Prime Standard Edition Handbook Volume 1 Design and Synthesis:

Preserves post-fit results for the partition and reuses the post-fit netlist when the following conditions are true:

• A post-fit netlist is available from a previous fitting.
• No change that initiates an automatic resynthesis has been made to the partition since the previous fitting.

When a post-fit netlist is not available, the software reuses the post-synthesis netlist if it is available, or otherwise compiles from the source files. Compiles the partition from the source files if resynthesis is initiated.

The Fitter Preservation Level specifies what level of information is preserved from the post-fit netlist.

Assignment changes, such as Fitter optimization settings, do not cause a partition set to Post-Fit to recompile.
