Question

Question 3: a) i) Design a 1-bit full subtractor circuit. ii) Show how the circuit in part a)i) above can be used to design a 4-bit subtractor circuit A-B. Draw the circuit and explain briefly its operation assuming that A=1001 and B=0110 b) For the circuit shown in Fig.Q3 write a Verilog code that describe this circuit. Use continuous assignment statements. Your code should include module definition, port declaration and any other syntax required to synthesize the code. c) i) Design a 1-bit full adder circuit. ii) Design a circuit that computes F = 7I, using the fewest number of adders. Input I is a 4-bit number. How many bits are required for the result to avoid overflow?
