1. Calculate the combinational 0-controllability,1-controllability and observability measures for all signals (inputs, outputs, or internal nodes) in a 4-bit ripple-carry adder (RCA).An Example RCA Is shown below:
2. Consider the example pipelined RCA Shown below. If full-scan is used to replace each flip-flop with a scan flip-flop, what are the maximum combinational 0-controllability,1-controllability,and observability measures for allsignals(inputs,outputs,or internal nodes)in a 4-bit Pipelined RCA.Consider a pseudo primary input to be equivalent to a primary input and a pseudo primary output to be equivalent to a primary output in the calculation of these maximum controllability and observabilitymeasures.
3. Similar to the diagram that is shown below, what sequence of signals is required to set the sum to "1110" When A="0110" and B="1010"?
