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

    if(J==0 && K==0) Q<=Q;

    else if(J==0 && K==1) Q<=0;

    else if(J==1 && K==0) Q<=1;

    else if(J==1 && K==1) Q<=~Q;

end

endmodule
