data logging via JTAG?

Hi.
I have a simple board with an Spartan 3 FPGA and a AD connected to it.
The board is configured via JTAG using the Xilix Platform Cable USB (24
Mhz). What I would like to do is to capture the data from the A/D
converter to the computer via JTAG. Does anybody know of a good way to
do this with the Xilinx applications (Chipscope, System Generator,
etc)? Or maybe with a 3rd party tool?

I appreciate any information,

JAn

The easiest why to do this would be with a ChipScope ILA core with
the data bus connected to your ADC interface.  You will be able to
use the graphing option in ChipScope to visually display the data
as well.

If you're only want to look at the ADC output in human time, as
opposed to cycle-by-cycle, you could use a ChipScope Virtual I/O
(VIO) core instead of an ILA.  You won't be able to graph it, but
it can display it any radix and scale that you want.

Hi Jan,

Have a look at Dialite (http://www.temento.com/solutions/fpga.php). This 
product allows you to add instruments like monitors/switches etc at the RTL 
level which you can then interrogate/control using either a GUI, 
TCL/C++/Perl or (D)COM interface. The interface is either the native FPGA 
jtag TAP or a customer one. I believe that FS2 (http://www.fs2.com/) 
provides something similar,
