Therefore with increase in combinational delay leads to decrease in operating frequency. One of them is Kogge Stone Adder , one of the fastest adders available.

Below is the schematic diagram of 4 bit Ripple Carry Adder.

Disadvantage of Ripple Carry Adder: Many more adder architectures are developed by researchers. Leave a Reply Cancel reply Enter your comment here Rerun the simulation and observe the output in the console of the ISim application: We will now create a new Verilog module called MultiStages. The idea is simple. We want to add a 4-bit word to another 4-bit word and get a 4-bit sum, and a carry out. All we need to do is write Verilog code that will replicate the full-adder encapsulated in SingleStage 4 times, and let the carry ripple from one stage to the next.

You should be able to recognize the main features of the test module by now. The one that might be surprising is the for loop. Retrieved from " http: Navigation menu Personal tools Log in. Views Read View source View history.
