Size of bi/bit file from bitstream

Jump to solution

Hi,

 In my project I am generating bitstream/ bin file in compressed format. 

For loading the bin stream to FPGA i would like to know the size of file in prior.

Is it possible to judge the size of bit/bin file from the header?? In this case by reading this info I can determine the size to write.

Hi @rakeshm55 ,

Xilinx will not guarantee customer about the amount/% of compression done to Bit file. Hence you cant know size of Bit file, prior to Bit File generation. 

In bit File header you cant find information about size of the file. You can find the size of the Bit File in Impl_1 Folder of your project after Bit file is generated.
