43. Guard Division by Zero

How do you plan to solve it?

raising flag if the divisor is zero

Note : synthesis isn't working 

module safe_div8 (
    input  [7:0] dividend,
    input  [7:0] divisor,
    output [7:0] q,
    output [7:0] r,
    output       div_by_zero
);
    // TODO: implement with ternary (?:)
    assign div_by_zero = (divisor == 8'd0) ? 1 : 0;
    assign q = (divisor == 8'd0) ? 8'd0 : (dividend / divisor);
    assign r = (divisor == 8'd0) ? 8'd0 : (dividend % divisor);
