WebIf you're trying to detect an edge on an input, such as for an interrupt detection, the recommended way is to synchronise the edge to an internal shift register. It could be as simple as this: reg [1:0] det_edge; wire sig_edge; assign sig_edge = (det_edge == 2'b10); always @ (posedge clk) begin det_edge <= {det_edge [0], input}; end WebVerilog Clock Generator Simulations are required to operate on a given timescale that has a limited precision as specified by the timescale directive.

WebOct 4, 2024 · This code generates HIGH output for 8 clock cycles as it detects positive edge of enable (as it seems to be what the problem asks). As it is clear from your problem description, logic, and attempt, you do not need count as an input (you cannot initialize your input, because they are triggered from outside of the module).
