How to generate a gray counter test pattern?

[no_mad]

Hi,

Any ideas on how to generate a gray counter test pattern.

NOT generate stimulus for gray counter.

One way is

initial begin

inputA = 3'b000;
#20;
inputA = 3'b001;
#20;
inputA = 3'b011;
#20;
inputA = 3'b010;
#20;
.
.
.
.
.
inputA = 3'b100;

end

Is there any other way to do this? Any ideas.

Thanks in advance.
