How can I Preserve the Fitter Result of single module in a whole design?

[SYiwe]

There're several modules in my design, one of them(module A) achieves design goal after the latest compilation.

So I want to prevent the Fitter result of module A from being changed in the future, while the other modules' source file will be modified.

The point is, I didn't set module A as a partition before the latest compilation.

Is there any way that I can keep the Fitter result of module A completely unchanged?

Thanks, regards.

Hi, you can implement Design Partitioning to preserve the synthesis or fitter result.

You can refer to the reference guide below:
