Hi I want to debug a custom board with no interface for data exchange. The requirement is PC based autometic test pattern generation and real time data exchange from FPGA based hardware.
I chanced to see an article in Xcell Journal of 2nd quarter 2005, titled: "Using the JTAG Interface as a General-Purpose Communication Port"--- but couldn't find any thing from the link given in the article.
How can I get GNAT tool as described in that article.
Or
Any other suggestion to use JTAG of Xilinx FPGA as general purpose I/ O.
regards MH
