WebSep 2, 2024 · If you want to use negedge reset then you can use: always@ (posedge clk or negedge rst) begin if (~rst) // do the reset else begin // your normal execution logic end end Other than that, there is nothing complicated on reset. Both on these occasions, on posedge / negedge of rst, block will get triggered and it will do the reset.
