I have code for cryptanalysis of AES(128 bit ) want to implement it on virtex5 board using core generator...
I generate BRAM and FIFO using core generator, and read data from text file as input for code also write output to text file....
output is seen in simulation result but write file shows 0000000....00000 value not the output value seen in simulation result...

help me

Thankx



core generated BRAM code and core generated FIFO is below

How is this posted code supposed to tell us anything. From your own description it's a problem with the testbench you wrote that isn't writing the values out to a file. Post the TESTBENCH not the cores.

What is with the people that post on this forum, don't they understand that none of us are psychics and we don't own crystal balls (at least I don't).
 

thank for reply, now below is my testbench code
read value as ip is

"000102030405060708090a0b0c0d0e0f"
Click to expand...

output key is

"0000000000000000000000000000012b"
Click to expand...

which shown in simulation waveform but not write.
in simulation firstly set rest to 1 and then to 0.

Good luck fixing your problem.
