partial reconfiguration RBF file size

Hi, I'm using the Arria 10 and QUARTUS 19.4. The rbf size of my full version is 30MB and the persona is 90MB. How do I affect the size of the persona rbf file? Thanks Liron

Hi Ash,

Which modes can I choose?

I have seen that there is a SCRUB mode, but I can not find where to run it.

Can you help me with that?

Thanks,

The SCRUB mode you're thinking of refers to the old Stratix V flow, not your device.

In general, for Arria 10, the final bitstream file size and time to reconfigure your design is proportional to PR region height. The easiest thing to do to shrink .rbf file size is to make your PR regions shorter in Y and wider in X. This gets into how the device masks off SRAM bits to not reconfigure parts of the design and the way CRAM bits (configuration RAM) are set.
