WebFeb 13, 2024 · The module should produce an output every cycle. All flip-flops, if any, should be triggered on the rising edge of the clock and resets should be asynchronous. The only way this would work (i.e output is provided on the same cycle as the input is seen) if there are no flip-flops in the module. WebThis nominally works as a wire for clk_sub is automatically created, there is a danger to relying on this. it will only ever create a 1 bit wire by default. An example where this is a problem would be for the data: Note that the instance name …
