WebApr 3, 2015 · For your case, you want asynchronous reset. Asynchronous reset means that your circuit should reset whenever reset signal is active 'Irrespective' of clock. Naturally, this should be included in the sensitivity list. always @ (posedge clk, negedge reset_n) begin if ( 'reset_n) //Then reset (active low). else // Do something else end Share Cite WebThe reg data type holds a value until a new value is driven onto it in an initial or always block. The reg type can only be assigned a value in an always or initial block, and is used to apply stimulus to the inputs of the DUT. The wire type is a passive data type that holds a value driven on it by a port, assign statement or reg type.
