Using the full adder already designed as a block, design an 8-bit ripple carry adder. a) Add 3 splitters to circuit. Each splitter should have an input width of 8 bits and a fan out of 8. b) Attach two east-facing splitters to the 8-bit inputs A and B. c) Attach a west-facing splitter to the 8-bit output S. d) Create eight instances of the FA circuit. e) Connect the S outputs of the eight FA instances to the splitter for the 8-bit S output. f) Connect the carry inputs and outputs of the eight FA instances so that carries will propagate appropriately from the Ci input, through the 1-bit adders, to the Co output. g) Connect the A inputs of the eight FA instances to the splitter for the A input. h) Connect the B inputs of the eight FA instances to the splitter for the B input. 1) Test your circuit. 1) Finally save your design as 1 module or sub-circuit for future use.
