FPGA to PC ??

Hi,

How do I want to trace or read my FPGA code which has been downloaded to the FPGA. In other words, to read FPGA code to PC. I want to keep that coding as my reference. I'm working with Xilinx software.


Thank you
 

Re: FPGA to PC ??

Do you want to read HDL code or gate level circuit?
 

Re: FPGA to PC ??

Hi,
I want to read HDL code. I really want to keep that coding as it is my original code. I'm not very sure how to read the HDL code to my PC.

Most people they download HDL code to FPGA, but my case FPGA to PC.
I hope it is clear.

Thank you

The code downloaded to an FPGA is a binary configuration bistream rather than HDL code. As long
as the configuration isn't encrypted, you would be in principle able to recover the gate level netlist
from the bitstream. But the netlist is far from readable HDL code.

Hi kedah_man,

Once the code is implemented in the FPGA, there is no return back. You can not read the original HDL code. Actually, the synthesis process converts the HDL code into a gate level netlist.
