Fsm1

This is a Moore state machine with two states, one input, and one output. Implement this state machine. Notice that the reset state is B.

This exercise is the same as fsm1s, but using asynchronous reset.

Module Declaration

module top_module(
    input clk,
    input areset,    // Asynchronous reset to state B
    input in,
    output out);
//  

    parameter A=0, B=1; 
    reg state, next_state;

    always @(*) begin    // This is a combinational always block
        // State transition logic
    end

    always @(posedge clk, posedge areset) begin    // This is a sequential always block
        // State flip-flops with asynchronous reset
    end

    // Output logic
    // assign out = (state == ...);

Yes, there are ways to do this other than writing an FSM. But that wasn't the point of this exercise.
This is a TFF with the T input inverted.
