A logical operation circuit device includes a number of exclusive AND/OR logical elements derived from the logical formulas associated with a full added/subtractor. The arrangement provides a full adder/subtractor for operating on one-bit binary digital signals.SUZUKI,YASOJI...
);//This circuit is a 4-bit ripple-carry adder with carry-out.assignsum = x+y;//Verilog addition automatically produces the carry-out bit.//Verilog quirk: Even though the value of (x+y) includes the carry-out, (x+y) is still considered to be a 4-bit number (The max width of ...
