1. Introductory Material

This section introduces the project, abstract, acknowledgements, problem statement and solution, operating environment, intended users and uses, limitations and assumptions, expected end product and other deliverables.

1.1 Executive Summary The scope of this project is to expand upon previous Teradyne J750 cookbooks of instructions which are in a manual format for the ISU Department of Electrical and Computer Engineering. At present the current cookbook instruction set is missing a mixed-signal volume section and the present project team members fills this gap by reviewing, citing previous cookbooks to meet the mixed-signal testing requirements requested by the ECpE department to create an extended cookbook. The team will setup and test (2) two (10) ten to (12) twelve bit ADC’s, (2) two (10) ten to (12) twelve bit DAC’s, and a (10) ten MHz or faster op-amp using the Teradyne J750. The test scenarios and documentation will be used to create this mixed-signal cookbook.

1.2 Acknowledgement

The team members extend great appreciation and would like to this opportunity to thank Dr. Robert Weber for the advisory role and being very committed to the team and this project through out its duration. The team also likes to acknowledge and thank Jason Boyd for the training and on site supervision for the first scheduled month after the initial meeting with Dr. Weber of the project as well as the department of Electrical and computer engineering at Iowa State for use of the Teradyne J750 and the Teradyne Company for the J750 tester. Lastly the team would like to acknowledge the previous senior design teams for the documentation that is left in the lab to be used as a source of reference on this project.

1.3 Problem Statement and Solution

This section gives a general outline and an overview of the proposed problem solution.

1.3.1 Problem Statement

The success of any product for the market after the planning and fabrication phases relies heavily on some form of testing and experimentation. The product must undergo some form of rigorous tests for different scenarios before release to ensure that is functions according to specifications and the client expectations. Universities and colleges which are research oriented provide a cost effective way of testing such products for companies and investors. Iowa State is no exception and with the donation of the Teradyne Integra J750 tester from the Teradyne co-

5

operation, it gives Iowa State department of Electrical and computer engineering this opportunity to achieve this cost effective way of testing and building devices.

6

This is important because the research conducted can create new methods of testing and also increase or build upon the productivity of the equipment donated and the devices under test. The associated cost of obtaining a fully functional tester is beyond the university’s operating budget and the present Teradyne J750 does not have the capability at present to perform mixed-signal testing. The two past groups have already designed, tested and implemented digital circuits as well as wireless circuits for testing along with the original function of the J750 to test analog circuits. The present team must design analog to digital converters and configure the Teradyne via hardware configuration and software to have the capability to test these mixed-signal IC circuits.

1.3.2 Problem Solution

The team will devise a way to interface mixed-signal components with the Teradyne J750.  Code will also be written using IG-XL software that will be compatible with three different breeds of devices; a DAC, ADC, and high speed operational amplifier. Once this is setup, methods for testing the devices will be developed and recorded in an orderly fashion.  These records and testing procedures along with the results will then be brought together in one concise package.   This package will be added on to the current Teradyne J750 cookbook and will show users how to setup and test mixed-signal devices using the machine.

1.4 Operational Environment

Operation of the circuits has to occur indoors within a temperature range of 27°C to 33°C because of the sensitivity to temperature the Teradyne J750 own circuitry possesses and the fact that the equipment itself is worth over 500,000 US dollars, maintains why a preventative process needs to be followed before operating the machine. Thus the Department of Electrical and Computer engineering will only operate and test the various circuits for mixed-signal in a temperature regulated room. The presence of a human body presents the opportunity for the distribution of charge and voltage to any form of circuitry .i.e. (ESD – Electrostatic Discharge) and which can have an adverse affect on the equipment similar to temperature. It is required that every person and team member that is present in the room who is in direct contact with the Teradyne J750 wear ESD wrist bands when using the tester. The vacuum pump and the “on” portion of the on/off switch are to be activated before any form of testing can be done after the first two instructions above are done. The purpose of the vacuum pump is to allow the DIB and the tester surface to be held together safety with approximately (4) four psi of pressure so that the both interfaces are locked together so the other devices that needs to be mounted can be done and held in a stable position for the process of testing.

1.5 Intended User and Intended Use

Section defines who are the intended users and the intended uses of the project.

1.5.1 Intended User

The potential audience for this project will be any student or faculty member of the Department of Electrical and Computer engineering that requires testing of the mixed-signal option devices. The user must possess some form of knowledge of IC circuits; digital logic, signals and digital communication, and an understanding of the operation the Teradyne J750 for conducting tests. The user must be able to synchronize the frequency that controls clock cycle along with the rest of setup and be able to follow the reference manual developed by the design team.

1.5.2 Intended Use

The intended use of the project is to allow mixed-signal testing using the Teradyne J750 tester and to develop and test various scenarios for (2) different (10) ten to (12) twelve bit ADC’s as well as DAC’s and for a (10) ten MHz or greater op-amp. This mixed-signal option provides an innovative approach to these microcontroller mixed-signal devices similar to the present industry testing capabilities and using the IG-LX software provided is able to efficiently record the results from the tests so as to achieve the goals of the Department of Electrical and Computer engineering.

1.6 Assumptions and Limitations This section outlines the expected assumptions and limitations for the end-product where any additional assumptions and limitations to be included prior to team or advisor consultations about specifics of the project.

1.6.1 Assumptions This section provides the relevant details of the user and system assumptions.

1.6.1.1 User Assumptions This section outlines the assumptions about the intended user:

Willing and can follow basic instructions during training to use the equipment so as to follow all necessary safety precautions.

User has read and understood the Teradyne J750 instructional manual. Some form of electrical and/or computer engineering background. Previous experience in circuit testing with the Teradyne J750

8

User is knowledgeable of the electrical hazards the equipment can distribute and what the user is at risk of transferring to the machine.

User treats and operates all equipment in a timely and professional manner.

User is familiar with technical English as all documentation at present is/will be written in English.

User is knowledge about mixed-signal operation and concepts. User is able to tolerate the noise caused by the vacuum pumps.

1.6.1.2 System Assumptions

This section outlines the assumptions about the overall system:

All instruments are operational and calibrated. No expired licenses or copyright material that the team does not have

permission to use. The vacuum pumps are always operational. Testing of DUT’s are limited to one at a time. Teradyne J750 can interface with the IC devices to be tested.

1.6.2 Limitations

This section will provide details of the limitations identified with the project:

The Teradyne J750 is sensitive to temperature fluctuations and must operate within of the calibrated temperature. The current system is set for .

The Teradyne J750 is only capable of testing digital I/O. Because of this, all chips tested with the wireless interface must have digital I/O.

The maximum rate at which user can send data is at 115.2 Kbps The existing transmitter and receiver communicate at 916.5 MHz.

Therefore, nearby wireless signals at similar frequencies may disrupt the setup.

The communication link shall be limited to one frequency. The IG-XL software shall be used in writing the test code for the Teradyne

J750. The distance between the wireless interface and the Teradyne system will

be limited to five feet.

1.7 Expected End-Product and Other Deliverables

This section outlines the details of the expected end-product and other deliverables.

At the conclusion of the Fall 2006 semester this project will bring into being: The five different IC interfaces constructed for review by Dr. Weber. IG-XL code written for each of the five IC interfaces for review by Dr. Weber.

At the conclusion of the Spring 2007 semester this project will bring into being: A complete Teradyne J750 cookbook which documents mixed-signal IC circuits. A demo test of the five different IC interfaces as instructed using the Teradyne

J750. These include the (2) two different (10) ten to (12) twelve bit ADC’s and DAC’s and a 10 MHz or greater operational amplifier.

2. Proposed Approach and Statement of Work

The proposed approach and statement of work will entail all of the necessary actions needed to ensure the success of the project.

2.1 Introduction

This section will descried the expected end product and other deliverables by breaking them down into subsections that addresses constraints, functionality, technology, and other important issues.

2.1.1 Functional Requirements

The following describes the functional requirements of the end product:

       The cookbook will be written on a level that the uninformed test engineer can understand

       The testing instructions will address two ADCs, two DAC’s, and an Op-amp faster than 10 ten MHz.

       Only one DUT will be tested at a time.       A test program will be developed for each of the devices using IG-XL and

will allow new devices of similar constraints to be added.        Upon successful testing and mating of the devices a cookbook will be

made to allow future users to test these devices.        If the project fails, proper documentation will be provided such that one

can look over potential problems and issues.

2.1.2 Constraint Considerations

The following will define the constraints considerations of this project:

        30 weeks are allowed for the completion of the project.        The room housing the Teradyne tester is accessible by security code only.        All documentation and users manuals will be in English.        The total allotted budget for the project is $150.        Testing is done by digital I/O.        The software used for project will be developed using IG-XL.       The operating environment has to be kept at a constant. temperature of

30°C ± 3°.        Mixed signal testing is needed to test the devices.

11

2.1.3 Technology Considerations

    This section covers any technological issues and ideas needed to interface the required devices with the Teradyne J750. Two different DAC's and two different ADCs will need to be tested along with a high speed op-amp.   The devices chosen will need to:

        Meet cost requirements        Proper connection to the DIB        Must be compatible with the Teradyne J750's I/O

Good care should be taken to ensure that the two DAC's differ from each other so that they can create different testing scenarios and the same goes for the ADC's.   The availability of cheap DAC's and ADC's components that are compatible with the Teradyne J750 and that can meet the team’s budget is limited.  The team will also have to take into consideration the DIB's that Iowa State already owns are also compatible and to test to see if it will work with the devices designed by the team.   Thus if a device is not compatible with one of the DIB's then the team will have to design and fabricate its own DIB.

2.1.4 Technical Approach Considerations

This section will detail the methods used for testing the devices. The best approach to testing the devices is to break the project up into smaller stages. This minimizes the overall risk and will help up successfully progress through the project.  It will also aid in troubleshooting and keeping track of where the team is in the scope of the total schedule.  Each stage will include the components of design, simulation, implementation, and testing.  Each stage will also have to be completed before any movement onto the next stage, with the exception of a few being run in parallel if time constraints become an issue. The stages are set up with the statement of work and can be followed easily using the Gantt chart designed for the project.

2.1.5 Testing Requirements Considerations 

This section will cover the testing requirements that need to be met in order to ensure that the device being testing is communicating with the DIB and the DIB is communicating with the tester.

Test one of the previous projects to ensure that the Teradyne J750 is still communicating with its DIB.   The test should meet the results produced by the previous team.

Run possible tests on the devices using instruments other than the Teradyne J750 to ensure that the devices are working to specifications.

Test the total setup by comparing the signal sent by the software to the signal received by the tester.

12

Run a TDR to make sure that all connections are valid so that any component of the Teradyne J750 cannot be damaged by faulty connections.

2.1.6 Security Considerations

Some security issues need to be taking into considerations in the process of developing the product. The major security concern in developing this product is to assure that we are obeying certain frequency bandwidth in order to not violate the FCC regulations. Since possible interference with other signal frequencies used by other communication networks might occur. Documentations are not of prior concern since increasing the knowledge of this product would be beneficial to other users.

2.1.7 Safety Considerations

This product will be operating under low voltage and current conditions. There would be no life-threatening concerns in the use of this product, maintenance or disposal possibilities. Although user of ESD wristband is recommended to avoid possible electric shocks which might damage the equipments and could lead to more financial issues in buying new equipments and extra effort to get the product back to the same stage. A figure of this ESD strap is shown below.

Figure 2: ESD strap

Basic steps in running the tester need to be taking under consideration to avoid device damage and misinterpreted results. in order to maintain device safety and insure data accuracy, turning the pump, switching on the tester, and then turning the computer on are basic steps that need to be performed in the same previous steps order. Also, the pins (I/O channels) need to be treated carefully while placing the test boards on top of the pins to ensure that they will not bend over which would cost money in order to replace them.

13

2.1.8 Intellectual Property Considerations

Both the design and the software for this product will be open to public use but only certain faculty members and students have access to the Teradyne lab which is located in Coover Hall.

2.1.9 Commercialization Considerations

If the team suggested building a new DIB instead of using the ones owned by ISU, This DIB might have a great possibility to be introduced to the market in order for the companies to use it. High volume testing of wireless systems is becoming a necessity for most of the companies and this product would be of a great benefit to achieve that.

2.1.10 Possible Risks and Risk Management

Different design risks may encounter throughout the progress of accomplishing a successful design project. Below are some of these possible risks along with some possible suggestions to avoid these risks.

Risk: Developing the (10) ten to (12) twelve bit ADC’s to be tested might fail to give accurate results.Management: (10) ten to (12) twelve bits ADC are pretty high resolutions. To avoid digital noise on the analog signals, the addition of a separate voltage supply (about +5V) devoted just to the ADC and the photodiodes used as inputs. The ground for all of the above could be tied into one point where the power came into the regulator. With minimal bypass capacitors on the ADC inputs that might easily get stable readings.

Risk: In developing the (10) ten MHz Op amp to be tested, the desired frequency might not be generated accurately due to misinterpreting of the external RC model of the circuit which can cause op-amp instability. Management: Reducing the resistance value that makes up the RC circuit reduces the effect of the capacitance; this effect leads to the rule of thumb that high frequencies and low resistance go together. Input capacitance is easily compensated by adding a feedback capacitor into the circuit. The value of the feedback capacitor should be just large enough to achieve the desired overshoot response, because larger values cause a loss of high-frequency performance.

14

Risk: The team might lose or misplace some of the documentations.Management: Hard disks and hard copies will be used to limit the risks of losing any of the documentations. Also, the team will make sure that every member of the team has a copy of all the documents in case of emergencies where one of the members is not available for any reason.

Risk: Failure to meet the client (Iowa State) expectations.Management: The team agreed on having regular informal meetings to review the requirements and the work accomplished thus far so as to meet these requirements. Also, to discuss any further improvements that could be added even if it was beyond the requirements to maintain high project efficiency.

Risk: Facing possible learning and understanding difficulties.Management: Trying to assign different design aspects to each member of the team to achieve his/her own expertise in that area along with general understanding of all design aspects by the whole team. This way the team can guarantee to extend the limit of coverage of all aspects of the design conflicts.

2.1.11 Proposed Project Milestones and Evaluation Criteria

3.1 Personal Effort Requirements

The total contribution by each team member, in hours, is listed in the table below.  The hours listed are an estimated amount of time that each member will spend on each aspect of the project.   The table is broken down into problem definition, technology selection, end-product development, end-product testing, end-product documentation, and project reporting. The project will provide plenty of work to keep the whole team involved and will provided enough flexibility for unforeseen circumstances.   The team is made up of four electrical engineers who will each have to put some work into programming on the Teradyne and the webpage.  One team member will be dedicated to the webpage for simplicity reasons. A good deal of time during the first phase of the project will be dedicated to adapting to the Teradyne and setting up tests for the parts purchased.   The latter phase of the project will primarily involve running tests and modifying the cookbook which will require a larger time commitment.  Extra preparation during the first phase will definitely reduce the amount of time spent during the second phase.

3.4 Project Schedule

A Gantt chart is created to show the predicted schedule throughout the duration of the project. All the tasks and subtasks that are defined earlier in the statement of work are laid out in two separate Gantt charts, one for accomplishments and another for deliverables with the expected dates, the amount of time reflected for each task which accounts for both the difficulty of the task and the relative strengths and weaknesses of the team. The table below, Table 6, shows the schedule of deliverables for the project of fall 2006 semester.

4.2 Closing Statement

The Teradyne J50 can be a very powerful device given the right amount of funding and the members of this senior design team would like to present this low cost solution for testing mixed signal devices by utilizing some of the instruments already available at ISU. It is felt that the best way to do this is by expanding the current cookbook for the Teradyne J750 which in turn will allow ISU the ability to use this tester more efficiently. A mixed-signal option will increase their number of avenues for testing these devices and it is the vision of the team and its advisor Dr. Weber that this guide will be beneficial to future students and researches at ISU and that they will be able to follow suit in the future by using this developed guide to keep the tester up to date with expanding technology
