WebThe signal CLK will continue to oscillate between ‘0’ and ‘1’, as shown in the waveform. The corresponding concurrent VHDL statement will produce the same result. If CLK is initialized to ‘0’, the statement executes and CLK changes to ‘1’ after 10 ns. WebThe baud rate is the rate at which the data is transmitted. For example, 9600 baud means 9600 bits per second. The code below uses a generic in VHDL or a parameter in Verilog to determine how many clock cycles there are in each bit. This is how the baud rate gets determined. The FPGA is continuously sampling the line.
