This is a Moore state machine with two states, two inputs, and one output. Implement this state machine.

This exercise is the same as fsm2s, but using asynchronous reset.

 

module top_module(
    input clk,
    input areset,    // Asynchronous reset to OFF
    input j,
    input k,
    output out); //  

    parameter OFF=0, ON=1; 
    reg state, next_state;

    always @(*) begin
        // State transition logic
        state <= next_state;
    end

    always @(posedge clk, posedge areset) begin
        // State flip-flops with asynchronous reset
        if(areset == 1)
            next_state <= OFF;
        else case (next_state)
            OFF: if(j == 1)
                	next_state <= ON;
            else 
                next_state <= OFF;
            ON : if(k == 1)
                next_state <= OFF;
            else 
                next_state <= ON;
            default:
                next_state <= OFF;
        endcase
    end

    // Output logic
    // assign out = (state == ...);
	assign out = state == ON ? 1'b1 : 1'b0;
endmodule
