Design this Hamming code in verilog. Create one module for the $3-$to$-8$ decoder $($dec$3$to$8)$ and a top module $($hc$7)$ that instantiates dec$3$to$8$ and add all the XOR gates. In the Hamming code design, you should use all three levels of modeling at least once: dataflow $($assign$),$ behavioral $($always$),$ and structural $($instantiation$).$

Use the following testbench to run your simulation. Include the waveform.

reg clk$=0$;

always #$5$ clk $=$ ~clk; $//$ Create clock with period$=10$

initial $`$probe$\_$start; $//$ Start the timing diagram
