Solving Approach

How do you plan to solve it?

 

Code

module jk_ff (
    input  CLK,
    input  J,
    input  K,
    output reg Q
);
// Write your code here
    always @(posedge CLK) begin
        case ({J,K})
            {1'b0, 1'b0}: Q <= Q;
            {1'b0, 1'b1}: Q <= 0;
            {1'b1, 1'b0}: Q <= 1;
            {1'b1, 1'b1}: Q <= ~Q;
            default: Q <= Q;
        endcase
    end
