Consider the following variables in a system:I. A : a signed number with $(16,7)$II$.$ B : an unsigned number with $(12,5)$III$.$ C : a signed number with $(6,1),$where $($n$,$m$)$ represents a $2$s complement n$-$bit number with m bits for the fractionalpart. Write a Verilog code that implements the following functionD $=$ A $+$ B$.$C$,$where D is a signed number with the highest possible resolution.
