Hi Wan
1. I could not find the three control wires in the FPGA UCF file.
You are quite correct, there was an error recently introduced into the
ROACH base ucf, which should now be fixed (r1985).
2. After I add the three control wires into UCF file, I could not see
the clock output from FPGA.
I'm not sure what you mean here, please give more precise and detailed
info of what you have and are doing. Do you have the ADC plugged into
the ROACH with the sampling rate at four times the fabric rate? Do you
have a led flasher application with an LED attached to counter? The ADC
clock should always come through, provided there is a external clock
plugged into the adc board, regardless of adc configuration status. If
you are really stuck try modifying the EDK project to hook a counter
directly onto the adc0_clk and attaching an led to the counter MSB.
Anybody had used the ADC card with Roach?
I been using the iADCs with ROACHs for about 7 months.
Good luck.
Cheers,
David
