43. Guard Division by Zero

How do you plan to solve it?

module safe_div8 (
    input  [7:0] dividend,
    input  [7:0] divisor,
    output [7:0] q,
    output [7:0] r,
    output       div_by_zero
);
    assign q= (divisor==8'd0)?8'd0:dividend/divisor;
    assign r=(divisor==8'd0)?8'd0:dividend % divisor;
    assign div_by_zero=(divisor==8'd0)?1'b1:1'b0;
