Hi Ftiglius,

Which FPGA device are you referring to? The .sof file(.rbf/.rpd bistream) size is fixed for all FPGA device. You can refer to the respective FPGA device datasheets and find a table that contain Uncompressed Configuration Bit Stream Size (bits). Then you should be able to estimate the total number of .sof files that can fit into the EPCQ64 flash device.
