Hi ,
i tried yesterday to configure my fpga with an encrypted bitstream . Using Impact 10.1 i didn't unerstand the way to do it , i mean how can i enter the key & bit files ? i couldn't find the option . what i did is to load the key file first inside fpga then the bit file , i v had the warning : Impact can not find the instruction ISC_Prog ...
thank you .
Im using : - Xilinx Platform cable USB II - OS : Linux - HW : Virtex 5 LX 30
- ISE 10.1
This was a problem in ISE 9.2.x. It was in the answer records on how to fix it. Here's the link:
I ran into the same problem under 9.2.4. I followed the instructions and manually updated my BSDL files and then my part programmed "fine".
Morphiend , Thank you ! But unfortunately this solution doesn't fix my problem definitly , in fact i v got a new warning :

Hi ,
Everything works fine when i implement the unencrypted design , so what's the problem with the crypted one ?!
