HBLbits_Verilog Basic_Fsm2s

HBLbits_Verilog Basic_Fsm2s

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

This exercise is the same as fsm2, but using synchronous reset.

module top_module(

    input clk,
    input reset,    // Synchronous reset to OFF
    input j,
    input k,
    output out); //  

    parameter OFF=0, ON=1; 
    reg state, next_state;
    always @(posedge clk) begin
        // State flip-flops with synchronous reset
        if (reset) begin  
            // Fill in reset logic
            state <= OFF;
            out = 0;
        end else begin
            case (state)
                // Fill in state transition logic
                ON: next_state = (k)? OFF : ON;
                OFF: next_state = (j)? ON : OFF;
            endcase
            // State flip-flops
        state = next_state;  
        case (state)
            // Fill in output logic
            OFF: out = 0;
            ON: out = 1;
        endcase   
    end
