Re: fpga emulation

Can you tell me the cable that you are using to download your bit file.Usually it should be a Xilinx platform cable.

Re: fpga emulation

it is the cable provided by the kit vendor itself. i dont remember its specification

Re: fpga emulation

OK then do you get an error window in imapct asking you to check cable connection and the voltages ???? If the error message tells you to check for voltages then it could be problem with the JTAG chain.... And by the way have you installed the cable drivers in your computer????Does the LED in your programming cable glow and changes color when you connect it to your board?If either of the things does not happen then it is a driver issue..It will be better if you can paste the messages that you get in the console when you initialize the scan chain

i got cleared by myself. actually the problem is due to improper cable fixture between my PC and the FPGA board.
