WebDec 4, 2024 · Posedge reset reacts on positive edge of reset signal, that is transition from 0 to 1. Negedge is transition from 1 to 0. Which to use depends on whether the reset signal is active high or low. If it is active high ( reset=1 means it should reset), you need to react on change from 0 to 1.
