Dear Sir,

There have a Xilinx/Nallatech Virtex4 development board beside me, on
which there has 2 ch ADC (105MSPS), 2ch DAC, FPGA Vritex4
XC4VSX35-10FF668.

There have poor examples from Nallatech, and I really don't like the
interface FUSE. I am using the USB port to communicate with this board,
and if I want to configure the FPGA chips through USB, FUSE seems the
only way? (or I write the dirver for USB interface). Is it possible to
configure through JTAG directly in ISE?

I plan to make the board running, for example, a simple signal
generator, or digital filter. Can you give me some detailed instruction
on it? I am not good at HDL, good example start from ISE is very
helpful. Thanks

Hi,

We have this same board, and have used both the USB with the FUSE
software and JTAG through Impact in ISE to program it. There is a
connector on the board that fits standard JTAG programming cables from
Xilinx. There is a simple example program that comes with the board
showing ADC and DAC connections. You could use this with say a CoreGen
DDS or FIR filter with very little new VHDL.
