    and a(ta,S,nr);
    nor n2(Qn,Q,ta);
    nor n1(Q,Qn,R);

    // reg Q,Qn;
    // always @(*)
    // begin
    //     case({S,R})
    //         2'b00: begin Q=Q;Qn=Qn;end
    //         2'b01: begin Q=0;Qn=1;end
    //         2'b10: begin Q=1;Qn=0;end
    //         2'b11: begin Q=0;Qn=1;end
    //         default: begin Q=Q;Qn=Qn;end
