3. Design a 2-to-4 decoder using Verilog (VHDL).
4. Draw the truth table of the overflow/underflow detector while adding two fixed point numbers represented in 2’s complement.
5. Design the logic circuit in Verilog (VHDL), Design an SR latch.
6. State the truth table of the full subtractor. Design it in Verilog.
7. Design an 8x1 multiplexer using two 4x1 MUX, and Design 4 bit full adder circuit using four 1-bit full adders.
8. Generate G_i and P_i and S_i while adding two x_i, y_i and a carry C_i: Implement a 4-bit carry look-ahead adder.
9. Implement an 8-bit adder cascading two 4-bit carry look-ahead adders.
10. Using the case statement, design an 8-function ALU that takes 4-bit inputs a, b and 3-bit input signal select, and gives 5-bit output.
It implements the following function.

Select Signal Function
3’b000 out=a
3’b001 out=a+b
3’b010 out=a-b
3’b011 out=a/b
3’b100 out=a%b
3’b101 out=a<<1
3’b110 out= a>>1
3’b111 out=(a>b)


case ({s1,s0})
