By considering the price, spped advantage of USB is not so high. Also XILINX has more attention on Parallel Cable 4. So I suggest it is better than USB Multilinx
hi again
i would like to build one so i think there is a USB controller such as cypress 68013 and a s/w interface to download through USB on FPGA's JTAG .
but i know NOTHING about s/w interface?
Regards
In programming the FPGA config memory, for faster speeds, you have to use parallel programming modes, which would be faster than jtag by orders of magnitude, for example, you can check the programming time specified in various modes, as stated in xilinx datasheets.
