Use verilog to create a 32-bits accumulator requirement: this accumulator cannot directly apply verilog built-in addition operator for bit vectors, for example “assign {cout, s} = a + b + cin; ”. you need to design 2 different structure of accumulator: 32-bits ripple carry adder (rca) and 32-bits carry look-ahead adder (cla), and you can use different full adder architecture also
