a) Write behavioral Verilog code for a module called “HW6” (pictured below) with two inputs a, b and two outputs x, y defined as follows. Solution The figure is not visible. So considering the module as an Half adder which has two inputs a and b, with sum and carry as outputs module half_adder(a,b,cout,sum) input a,b; output cout,sum; sum= a+b; cout=a*b; end module.
