Web Guide For Completing Lab Work.

Week 1 Guide:
Introduction To the Digital Lab and Lab #1 Vending Machine System

Introduction To the Digital Lab

  • 1- No food or drink is allowed in the lab.
  • 2- There are no pre-lab assignments or lab work to complete outside the lab period.
  • 3- Each week you must bring the book and the red signoff sheet to the lab.
  • 4- Each week you must view this website to access the lab guide and design files.
  • 5- Lab work is verified and answers to lab questions are submitted by the end of each lab period. If you submit an incorrect answer, then you must access the blackboard website to see the correct answer. Answers to lab questions are posted in "Lab work" section of blackboard.
  • 6- When you see this icon you can click on it to get help with the theory covered in class.
    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.

    • Lab #1 Vending Machine System

     

    Use your student network drive "U:" or a memory stick (jump drive/flash drive) to complete the lab.

  • 1- You need a folder called "labs" to save files.
  • 2- Click here for the GDF file for Vending Machine System and place this file in folder "labs".
  • 3- Run the Altera Program:
  • 4- Follow the procedure (steps 1 to 17) on the orange laminated summary card to create/save/compile/configure the system onto a FLEX IC. If you wish to view a detail description of steps 1 to 17 you can refer to the procedure in the book on pages 22 to 29 and then 34 to 44.
  • 5- Demonstrate the operation of the system and get a signature from the instructor.
  • 6- Save all the files. The files are needed for the next the lab.
  • 7- Put your name on a separate piece of paper and answer questions 4, 5, and 6 found on pages 45 and 46 of the book. Submit the answers.

    Week #2 Guide:
    The ALTERA Simulator and Lab #5: Random Number Generator Lab.

     

    Use The ALTERA Simulator To Test The Vending Machine System.

  • 1- You need the vending machine files for Lab #1 from week #1.
  • 2- Use "Appendix F" of your book and follow steps 1 to 8 on pages 309 to 318.
  • 3- After step 8, demonstrate the simulation and get a signature.

    • Lab 5: Random # Generator.

    You need to understand the random number generator system for next week's lab.

  • 1- You need a folder called "labs" to save files.
  • 2- Click here for the GDF file for Random # Generator System and place this file in folder "labs".
  • 3- Right click here BCD counter VHDL file choose "save target as ..." and place this file folder "labs".
  • 4- Run the Altera Program:
  • 5- Follow the procedure (steps 1 to 17) on the orange laminated card to create/save/compile/configure the system onto a FLEX IC. Assign "Latch Enable" to a pushbutton. Assign "Oscaillator" to pin 91. Assign pin numbers to the LEDs. Assign pin numbers to the unused LEDs.
  • 6- Test the operation of the random number generator system and make sure it works.
  • 7- In this step you will slow down the pulse rate of the system so that you can see the counting on the LEDs. Currently, FD16 is used and it is very fast (192 PPS). You will need change the pulse rate of the BCD counter clock to 3 PPS. Replace the label FD16 with an FD number that will select a pulse rate of 3 PPS. Re-compile and re-program the Altera IC. Test the system. You should now be able to see the count sequence on the LEDs.
  • 8- On a piece of paper describe the function of each section of the random number generator system. Here is a list of the sections: LPM_counter, CountBCD, LPM_latch and latch enable pushbutton. Demonstrate the operation of the system, get a signature, and submit your answers.
