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
);
    wire a = |divisor; 
    wire [7:0] safe_divisor = a ? divisor : 8'd1; // Ngăn chia cho 0 nội bộ

    assign q = a ? (dividend / safe_divisor) : 8'd0;
    assign r = a ? (dividend % safe_divisor) : 8'd0;
    assign div_by_zero = ~a;
