On my test system, i have a USB cable from the PC to the 7i43 just for power, exactly as you say. The 7i43 does have a dedicated power input, so you dont have to use USB for power if you dont want to, just be careful because the 7i43 power plug looks like a "small ATX-style" power connector like you might find on a standard ATX power supply, but the pin-out is different. There is *currently* no advantage to getting the bigger 400 Kgate 7i43 vs the smaller 200 Kgate one. All currently available firmwares fit in the smaller FPGA, the limiting factor is I/O pins, not gates. In the future, there *may* be new firmwares that fit in the 400 but not the 200... For programming the device... If you're talking about sending a compiled firmware image to the 7i43, the hostmot2 driver does that when you start emc2. If you're talking about compiling custom VHDL code into a firmware image, the Xilinx software does that. -- Sebastian Kuzminsky ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
