Help with RBT file

RBT File. i am now trying to decode a RBT file, i am so confused abt how the data are stored in those frames. i am not sure how the address of each frame and the column are written in the RBT.

Hi Superman,

you need need to read the documents from Xilinx. I did. All the information you need is there. It really is.

Hi Antti,

Thanx a lot for the reply, I got a lot of information from the xilinx webpage, though there still remains 1 ques, which i do not understand.

after the FDRI is loaded with no. of the words that has to be written, the frames are being loaded with data right????......

like for eg:

On a virtex - II xc2v40. 30004000 --write 0 word to frame data input reg.; type

1. 50002922 --type 2,data words,0x2922 = 10530(decimal) = (404 frames + 1)*(26 words per frame)

then are 10530 line of bits....and here i do not understand how there data are arranged in frames..they do not match with description as said by xilinx.

Am i rite or i am decoding something wrong??????

if possible through some lite on this plz.

thanx 1 again.

I could say the same thing I said before: read the docu.

if multiply frames are loaded the the frame addr sub-fields autoincrement. The best thing is to generate a 'debug' bitstream' then each record contains each frame and you can see the frame addresses for each frame in sequence

but, why do you need to understand that stuff ?

Hey,

thanx for the reply, i am using it for partial reconfiguration.

if i send the partially decoded file, with comments would you be able to help me a little bit more, though i have read those docs, i am kinda confused. i understand that multiple frames or the whole FPGA is being loaded.

Well thanx 1 again for all those reply.
