in fact I use a microEnable grabber IV VQ4-GE contains a Xilinx FPGA, normally it is our supplier who programmed this card but has not delivered us the programs, then I want a solution to recover programs that are in the FPGA board

Yes, you can read out the Spartan3 net lists later on using JTAG, if you have the tools or a few kUSD spare and at least 3 months time to reverse engineer what is happening under the hood.. But for what you are targetting at: just forget it. You might want to get in touch with Silicon Software, if you want to modify vision components on your grabber.
