CSE370 Assignment 5

Distributed: 4 February 2010
Due: 10 February 2010


Reading:

  1. Katz/Borriello, Contemporary Logic Design 2e, Chapter 5, Sections 5.1 to 5.4 (pp. 221-234)
  2. Katz/Borriello, Contemporary Logic Design 2e, Chapter 6 (pp. 259-299)

Exercises:

  1. For the following problems, you may print the ROM, PLA and PAL worksheets or the worksheet that has all three on one page. Implement the following three functions using a ROM, PLA and PAL. For the PLA, try to minimize the number of AND gates you use (fewest terms overall for the 3 functions).
                                        g1(a,b,c,d) = ∑ m(1, 7, 9, 12, 13, 14) + d(3, 11)
                                        g2(a,b,c,d) = ∑ m(7, 9, 15) + d(14)
                                        g3(a,b,c,d) = ∑ m(1, 3, 9, 12, 14) + d(7)

  2. CLD-II, Chapter 5, problem 5.4
    This problem is based on the first exercise in HW#4.  You will now come up with a corresponding combinational logic implementation of your Verilog description.  For part c, only consider the logic of part b, not the ROM of part a. For this exercise, you can assume that all the inputs will be correct and you do NOT need to implement the ERROR output that was in the previous assignment.
  3. CLD-II, Chapter 6, problem 6.12
  4. CLD-II, Chapter 6, problem 6.19

Rationale:

  • To use two-level regular logic to implement combinational logic functions.
  • To start working with sequential logic elements.
