EECC 0306- 351: Hardware Description Language Lab LAB#5 The objectives of this lab exercise are: 1) To go through the design process of a behavioral and structural description of a control block (State Machine) for the serial adder. 2) To test the serial adder with the control block. 1) The state machine given below can be used as a control block for the serial adder designed in the previous lab. It is a Moore’s machine since outputs depend only on the current state. Implementation details for a Control Block entity inputs: outputs: (ready, reset_SA, s1, s0) start 1 bit clk 1 bit reset_SM 1 bit (asynchronous active high) control 4 bits

EECC 0306- 351: Hardware Description Language Lab a) Write a behavioral VHDL description of the state machine (2 or 3 processes). Use enumerated type to define the states (use the same names as in the diagram). Make your machine sensitive to the rising edge of a clock signal! b) Draw the schematic of the state machine using flip-flops and combinational logic gates (gates have 5 ns delays and DFFs 2 ns). Based on the schematic create a structural description of the state machine. Name all

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
