Hi
If have a few questions regarding the serial interface between the FX2
and the FPGA and the writing of registers. I would just like to know
how serial_strobe, serial_data and serial_addr signals work? I know
that serial_io.v handles this and generates a strobe to tell the
modules that something was written on the serial interface.
I would just like to know how these signals work. When does
serial_strobe go up and how is serial_data and serial_addr stored?
For now I want to write a testbench for phase_acc.v. I would like to
know how the serial input to this module should look in order to input
the address and a frequency value into this module and get it to
output freq. I want to then see what the phase output that goes to
cordic.v looks like in order to simulate cordic.v.
setting_reg #(FREQADDR)
sr_rxfreq0(.clock(clk),.reset(1'b0),.strobe(serial_strobe),.addr(serial_addr),.in(serial_data),.out(freq));
Thank you very much.
