how to verify the FPGA loading file manually

georgedu · ‎08-30-2013

Hi

I use the iMPACT to verify the FPGA downloading file and the tool shows it succeed

I notice iMPACT generate the iMPACT.rbd file .Then I compare this file with the original .rbd file (generated when bitgen )

Unfortunately ,this two file is quite different ,(I difff them in vim ）, Can anybody tell me the reason ?

Thanks in advance .

in the generated file by bitgen command ,the rbd file is :

Xilinx ASCII Bitstream
Created by Bitstream P.28xd
Design name: tri_1.ncd;UserID=0xFFFFFFFF
Architecture: spartan6
Part: 6slx45tfgg484
Type: readback
Date: Sat Aug 31 07:13:42 2013
Bits: 11872912
0000000000000000
0000000000000000
0000000000000000

and in the generated file by iMPACT：

1111111111111111

^@1111111111111111

I open these two in the vim
