This makes it easy for the CAD tools to map your logic onto the special-purpose arithmetic circuitry provided by many of today's FPGAs. unorthodox but I'm curious to know as I am new to Verilog. Using Table 1, write a Verilog program to implement a decoder that selects the proper input to the full adder depending on the sel signal. Designing a 4-bit ripple-carry adder Let us now design a 4-bit ripple-carry adder by stringing together four full adders (FAs).
