Verilog Implementation: Example 3: 4-Bit Carry Lookahead Adder in Verilog Note that the carry lookahead adder output (o_result) is one bit larger than both of the two adder inputs. This is because two N bit vectors added together can produce a result that is N+1 in size. For example,...

In VLSI design adders are the most critical components and attention should be focused in designing them.This paper deals with implementing carry look ahead adder with 4bits,8bits,16bits,32bits,64bits and 128bits using verilog platform.The designed carry ...
verilog:Modules-Adder-subtractor Temo 余生很长,且行且珍惜。An adder-subtractor can be built from an adder by optionally negating one of the inputs, which is equivalent to inverting the input then adding 1. The net result is a circuit that can do two operations: (a + b + 0) and (a ...
