while trying to understand the daq2 design with zc706 I need some help in understanding the gpis signals.
ADI always defines wires like this :
wire [63:0] gpio_i;
wire [63:0] gpio_o;
wire [63:0] gpio_t;
and then put it into ad_iobuf like this:
Why are you doing this, what the goal of the ad_iobuf ?
Why do you insatiate 64 wires but only 8 of them are used?
And what about the numbers behind the signals? where do they come from? Could they be any number between 63 and 0 with corresponding gpio_x [number] ?
