Schwartz Department of Electrical & Computer Engineering Professor in ECE Page 1/2 Revision 0 29-Aug-02 1:00 PM LAB 1: Introduction to Laboratory Equipment BEFORE YOU START Give your TA a piece of paper with your name (last name first), password (up to seven alphanumeric lower case digits [no symbols]) and your e-mail address. Please write your passowd carefully and clearly and make sure that zeros have a line through them ∅ to distinguish them from the letter O. You will use the password to view your grades throughout the semester. Keep it private unless you want others to know your grades. Write it down and save it. OBJECTIVES The objectives of this lab are to familiarize the students with the EEL 3701 lab prototyping environment, build strong debug techniques and demonstrate the Altera MaxPlusII circuit design/simulation software tool. MATERIALS • Printouts (required) of the web documents including this one, the “Hardware: Getting Started” document, the “MaxPlusII Tutorial,” the "Parts List,” the “Pinouts” document, and your prelab design and simulation. All designs and simulations done in pre- lab must be printed and brought to lab. All pre-lab material is turned in at the beginning of lab. You will not get this paperwork back until the following week. Since you are likely to need this material during lab, you must make a second copy for yourself before coming to lab. (This includes both computer generated printouts and hand written work.) • A toolbox containing the following will be given to you in lab. Verify that your box contains all the parts on your parts list. • Prototyping bread board, power supply, wires • IC components, resistors, LEDs and multi-meter INTRODUCTION The purpose of this lab is to illustrate the basic usage of the components founds in your toolbox and to test your ability to create a circuit in MaxPlusII. Read through all the printouts list in the materials section of this document. Parts I & III of this lab are informative only and do not require any pre-lab work. Part II however does have a pre- lab design for you to work through and this material will also be tested in lab by your TA. It is highly recommended that you take notes while your TA lectures or performs demonstrations. Feel free to ask question. You will be responsible for this all the material discussed. Part I. Using Your Toolbox Devices Your lab TA will demonstrate the following items contained in your toolbox. Verify that you can do the same with your parts. 1. Make sure the power supplier and the multi-meter work. 2. The electrical node connectivity of the prototyping board. I.e. power/ground buses & general signal rows. 3. How to place an IC (integrated circuit) device on the prototyping board and where power/ground are connected. Students should be able to find pin 1 on all their TTL ICs upon completing this short demo. 4. How to measure the supply voltage of the supply. Also, how to measure the voltage across a device once the device has been connected to power and ground. 5. How to use a multi-meter to determine the resistive configuration of the RPACK(s) provided in the lab kit. Once determined, draw this out and save it for future labs. 6. How to connect an LED to power (via a current limiting resistor). Measure the voltage drop across the current limiting resistor and diode and also the current through the circuit. Discuss why the current limiting resistor is needed and how it functions in the circuit. 7. How to connect an LED (again using a current limiting resistor) to the output (or input) of a TTL gate to test if it is high or low voltage. The TA should show you two circuits with LEDs: in one circuit the LED turns on when the output is a high voltage (active-high) and in the other circuit the LED is turned on when there is a low voltage (active-low). Draw and save both circuits. If an output signal is used to drive another IC input, why can’t we simply connect an LED to the output and the other end to ground or power, without using a resistor, in order to view the output signal voltage? Build and demonstrate an active-high LED circuit and and active-low LED circuit. 8. How to connect a pull-up resistor to the input of a gate to force a “high” on the input. Here is the basic connection: Input from another stage Output +5V
