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 pulse width of the output is derived by 10 bit data e.g., 0000000001 indicates 12.5ns pulse width 0000000010 indicates 25ns pulse width and there will be 6 bit input, through which we can select 8 output ports. when we select other signal, the previous signal should retain the data. entity pulse_gen is port (clk : in std_logic; freq_data ... WebDec 5, 2014 · Dec 5, 2014 at 15:52 If the counter should only increment on the rising clock edge the if condition should be changed to if (clk'event and clk='1') then .... Simulation would show you that twice the expected frequency is produced, because the original process will trigger on both rising and falling clock edges. – andrsmllr Dec 5, 2014 at 22:30 overnight cruise sydney harbour
