2) Mon., Sept. 17: 1. If the SOP form for f* = AB*C*+A*B, then give the POS form for f (where * means complement the preceding character) 
2. Use DeMorgan's Theorem to find f  if  f* = (A + BC)D + EF. (Do not expand, answer should have only one instance of each variable).

4a, 4b. Text problems 2.51 and 2.52 (3rd edition Verilog text) or 2.37 and 2.38 (in other newer editions). (Problem is only in newer editions. Questions say to implement the function in Figure 2.26 using 1) only NANDs, 2) only NORs.- Use figure 2.20 for 1st ed. VHDL text; use figure 2.24 for 1st ed. Verilog text

4) Wed., Sept. 26: Assignment is here.
5) Mon., Oct. 1: Use Quine-McCluskey (i.e., tabular) method to find a minimal SOP for the following:
  1) f(X,Y,Z) = Sum m(2,3,4,5);

Also determine Fan Out and Noise Margin for a 74L00 device driving 74L00 devices. Repeat for a 74L00 device driving 74LS00 devices. TTL spec sheet is here.
11) Mon., Nov. 5: 1) 4.1 in Verilog 3rd edition (6.1 in all other editions of the text) Do three ways: a) directly with no inversions anywhere b) least logic (smallest gate) c) decoder has inverted outputs; 
2) 4.4 in Verilog 3rd edition (6.4 in all other editions of the text) Use a 2:1 mux and no other logic (inverter is OK); 
3) Modified Fig. 4.21 (see note below) in Verilog 3rd edition (Fig. 6.25 in all other editions): a) implement segment "a" using an 8:1 mux and no other logic, b) implement segment "a" using a 4:1 mux and one other gate, c) implement segment "f" with 4:1 mux and no other logic. Note: The Verilog 3rd edition figure shows a hex-to-7-segment display and I want you to use a BCD-to-7-segment display as is given in the other editions of the text. Therefore, for that edition replace the last 6 rows of the table with don't cares.
12) Fri., Nov. 16: Verilog Edition 3: Chapter 5 problems 1, 2, 5, 7.
For all other editions: Chapter 7 problems 1, 3, 6, 8.
13) Mon., Dec. 3: Give a state graph and a state table for your design for Lab 2. This will be collected at the beginning of class with no late work accepted.
14) Fri., Dec. 7: Verilog Edition 3: Chapter 5 problems 15, 16, 17, 18
For all other editions: Chapter 7 problems 16, 17, 18, 19.

Lab Assignments:

Lab 1 -- Before coming to lab, you will need to download Altera Prime, Lite Edition. Select version 18.1, Lite Edition (so we're all using the same version). You'll need to create an account. In addition also download ModelSim and include Cyclone V device support. Useful files from text in case you don't have it with you.
Lab 2 Programming of board must be done and checked off during your lab period.
For debouncing the clock input, include the files DEBOUNCE.VHD and CLK_DIV.VHD in your project.
This C program can check your state table lab2check.c

Notes:

Some Knights and Knaves problems for fun   and with answers
K-Map examples from class  
Pairty checker (Moore & Mealy - done in class
Up/Down Counter done in class
Example sequence detector done in class. Both Mealy and Moore example
Implementation of the sequence detector using D-ff, T-ff, and JK-ff
Minimizing the number of states using row reduction
Minimizing the number of states using an implication table
A writeup on the State Assignments using the example given in class
Converting a Mealy to Moore and vice-versa.

FYI draw.io has a nice online way to draw state diagrams, flowcharts, etc. Let me know if you know of other (perhaps better) ways.
