Import Code from FPGA Board (Spartan 3E)

Is there any way to import code from an already programmed FPGA board, in this case, it is a Spartan 3E board. That is to say, verilog code has already been uploaded to it, so I would like a way to receive the code back in the computer since I have lost the copy.开发者_JS百科 I uploaded the code with Xilinx ISE, but am not sure if it is possible to go the other way around.

I really appreciate the inputs.

IF you mean the FPGA bitstream, Impact should be able to read it out. But if you want to get back to the source Verilog files... forget it, sorry!

(If it's a Xilinx board you can just download all the code it originally came with though :)
