牙齿和爪子:

7人表决器的测试代码如下：

[code=plain]

`timescale 1 ns/ 1 ns

module tb_voting();

reg a, b, c, d, e, f, g;

wire out;

voting U3(.a(a), .b(b), .c(c), .d(d), .e(e), .f(f), .g(g), .out(out));

initial begin

repeat(5) begin

a = $random % 2;

b = $random % 2;

c = $random % 2;

d = $random % 2;

e = $random % 2;

f = $random % 2;

g = $random % 2;

#10;

end

end

endmodule
