Digital Systems I: Continuing Education

Lab Guide and Lab Files

Week 1 Guide: Introduction To the Digital Lab
1- No food or drink is allowed in the lab.
2- Lab work is verified and submitted by the end of each lab period.
3- There are no pre-lab assignments or lab work to complete outside the lab period.
4- Each week you must bring the book and the red signoff sheet to the lab.
5- Each week you must view this website to access the lab guide and design files.
6- The Altera UP-1 system design kit is used to build and test all digital systems.
7- The UP-1 (university program) project board has a MAX and FLEX CPLD. We will be using the FLEX CPLD.
8- When you see this icon you can click on it to get help with the theory covered in class. Click on it and give it a try. To move forward through the presentation you need to press the {SPACE BAR} on the keyboard or click the mouse button. To move backwards you press the {BACKSPACE} key.

Complete Lab 2
Make corrections to the book:

1- Open your book to page 33 find step #11flex near the bottom. Write into the book the words "Uncheck the box "Show only fastest speed grades"".
2- On page 26 after the second paragraph write into the book the words "skip to page 33 for FLEX device".
3- On page 40 make the correction to the 10th line Change from"INPUT symbol pin17" to "OUTPUT symbol pin17".
4- On page 42 make the correction to Figure 2-54 shown below
5- On page 42 on Figure 2-55 Step 18 answer box write the words "See web guide diode diagram for a hint".
6- On page 43 find "Step 20flex" The second paragraph should say "Use steps 15 to 17 as a guide..."

1- You can use a floppy disk, a flash memory card stick (jump drive), or the student metwork drive (U:). Using the U: drive is the BEST option!
2- Complete the "Lab Work Procedure" on pages 20 to 26.
3- Skip forward from page 26 to page 33. Complete the lab work described on pages 33 to 43. The diagram below shows how the Altera board is configured with the logic gates.
4- You need to answer the question at the bottom of page 42. You can answer questions in your book or you can answer questions on separate piece of paper. The answer will be submitted at the end of the lab period. Answers in your book will be torn out and submitted. The question on page 42 (Figure 2-55) refers to "step 6 in Lab 01". You don't need to review Lab 01 if you know that Lab 01 proves the Altera LEDs are active low. Refer to the diagram below. It's the active low LEDs that make the system appear to NOT be working.
5- Fill in the tables at the bottom of page 43. The tables will be submitted at the end of the lab period.
6- Have the instructor test your system, sign your lab progress form, and collect your answers.
7- Remember to always exit the "Max-Plus II" program before logging off the computer otherwise you may corrupt the design files.

Week 2 Guide: Complete Lab 3.

Week 3 Guide: Complete Lab 5 VHDL Vending Machine System and Lab 6 VHDL Sound Meter System.

1- Read the description for steps 1 and 2 on pages 111 to 113.
2- You need the worksheet you detached from tutorial #4. You need to copy the table from the tutorial #4 worksheet into the table shown in figure 7-20 on page 112. To save time, only write out column "X".
3- Verify your table. The solution page is available at the front of the class room.
4- You need to create a folder called "U:\Lab07". VHDL only works when files are stored in a folder.
5- Before running the Altera MAX software, right click here drill VHDL file choose "save target as ..." and place this file in "u:\lab07".
6- Before running the Altera MAX software, click here Lab 07 GDF file for the VHDL Drill Machine System and place this file in "u:\lab07".
7- Run the Altera Max software and open the "lab07.gdf" file you downloaded then click the FILE menu, select PROJECT, and then SET PROJECT TO CURRENT FILE.
8- You will see a symbol for the drill machine. The symbol does not have the correct number of outputs because the VHDL code for the symbol must be changed. To change the VHDL code for the symbol "drill" you must double click the symbol. This will open up a text editor and allow you to make changes. Make the changes to the VHDL code now.
9- You must now create a new symbol. Leave the VHDL text editor open. Make sure you can still see the VHDL code that you changed. From the "File" menu select "Create Default Symbol". If Altera reports errors you will need to use the information on pages 87, 88, and 89 of the text to make corrections. Proceed to the next step if you are error free.
10- Shut down both the compiler and VHDL text editor windows. View the system diagram "lab07.gdf". You must update the VHDL Symbol. From the "Symbol" menu select "Update Symbol" and click the "OK" button. The symbol sound will now have the correct number of outputs.
11- Use the laminated orange card and complete steps 10 to 12.
12- Use the laminated orange card and complete step 13. Assign the 2 FLEX pushbuttons pins number 28 and 29 to start the drill. Assign 2 flex switches to simulate the cover sensor and the part clamped sensor.
13- Use the laminated orange card and complete steps 14 to 17.
14- To test the drill machine you need try all 16 switch combinations and place a check mark beside each table entry in Figure 7-20. Complete the system test now. - Once all 16 conditions have been tested then you need to answer the questions on page 114. - Tear out page 114 and place both your names at the top of the page. Demonstrate the operation of the drill machine system and get a signature. Bring these files back to the lab next week.
15- Remember to always exit the "Max-Plus II" program before logging off the computer otherwise you may corrupt the design files. These files will be needed next week to complete Lab 8.

Week 5 Guide: Complete Lab 8 SR Flip Flop. Both team members work together using only one computer station.

Week 6 Guide: Complete Lab 9 Shift Registers.

1- Make sure the "Max-Plus II" program is shut down. You need to prepare your computer for Lab 9.
2- You need to create a folder called "Lab09".
3- Before running the Altera MAX software, click here Lab 09 GDF file for the Shift Register System and place this file in "u:\lab09".
4- Run the Altera Max software and open the "lab09.gdf" file you downloaded then click the FILE menu, select PROJECT, and then SET PROJECT TO CURRENT FILE.
5- With partner #1 as the computer operator complete the work described on pages 137 and 138 "Test a 4-bit Shift Register WITH Switch Bounce". Remember to always follow the instructions for the FLEX IC Design. We never use the MAX IC. When you get to "step 3", in the middle of page 138 you must demonstrate the operation of the system and explain the diagram below.Get the first signature.
6- With partner #2 as the computer operator complete the "Lab Work Procedure" on pages 138 to 143 "Test a 4-bit Shift Register WITHOUT Switch Bounce". When this work is complete you must demonstrate the operation of the system and explain the diagram below. Get a second signature.

Week 7 Guide: Complete Lab 10 Serial Data Transfer System.

"Lab 13: "Binary Counter System".(Partner #1)

"Lab 15: "32-Bit" Frequency Divider System. (Partner #2)

1- Both team members must gather around the first system to complete observations for Lab 13. Test the operation of the binary counter system. The test is described on page 183 (step 4). Fill in the table and answer the questions shown in Figure 13-16. If you need help with "4count" theory, view the powerpoint presentation for lab 13 slide 5. Demonstrate the operation of the system, submit the answers, and get a signature.
2- Both team members must gather around the second system to complete observations for Lab 15. The test is described on page 207 and 208 (steps 4, 5, 6, 7, and 8). Answer all the questions. Hint: Use the diagram below. The diagram shows more detail and is equivalent to the Altera diagram. Demonstrate the operation of the system, submit your answers, and get a signature.
Assignment #7: Use the remaining time to work on Part 2 of Assignment #7. Here is the ZIP file .
