6th NATW to bring test issues discussion to Rhode Island

The 6th IEEE North Atlantic Test Workshop will be held May 29 - May 30, 1997 in West Greenwich, RI, USA. The workshop, which will focus on s20 Quality Designs and Tools for the 21st Century, provides a forum for discussion of the latest issues relating to higher quality, more economical, and more efficient testing methodologies and designs.

This year's workshop will open with a keynote talk by Don McInnis, CEO of SpeedSim Inc. Don's talk will discuss Business Issues Facing Test and EDA Tool Development and will provide an outlook on the future of CAD tools and the challenges ahead. We are also pleased to announce the inclusion of an invited paper on 0 Embedded DRAM Technologies and the test implications involved which will be presented by a team of leading DRAM technologists from IBM Microelectronics. The heart of the workshop, a day-and-a-half of technical paper presentations, will include the following interesting topics: BIST, ATPG, MCM testing, Fault Simulation, Testing Systems-on-a-Chip, Yield Prediction, Delay Testing, Memory Testing, Circuit Simulation, and IDDQ2 test approaches.

The 1997 workshop will be held at the Whispering Pines Conference Center, located on the W. Alton Jones Campus of the University of Rhode Island. The campus is situated on 2,300 acres of pristine forest and include streams, ponds, a 75 acre lake, and a nineteenth-century farm. It adjoins the 40,000 acre Arcadia and Pachaug State Forests. The Conference Center is a 30-minute drive from Providence, RI, an hour-and-30 minute drive from Boston, MA or Hartford, CT, and a 3-hour drive from New York City.ar

System Test Standards Committee Meets in San Diego

Last November, the IEEE Standards Coordinating Committee 20 met in San Diego, California, for the 2nd of two 1996 meetings. SCC20 gathers semi-annually to work on several standards related to system test and maintenance of electronic systems. While it is best known for the ATLAS standard, SCC20 also sponsors approximately 20 other standards projects under the management of six standards-writing subcommittees: 1. ATLAS which maintains IEEE Std 716 and IEEE Std 771; 2. Test Equipment Description Language (TEDL) which maintains IEEE Std 993; 3. Automatic Test Program Generation (ATPG) which is developing the P1445 Digital Test Interchange Format (DTIF) standard; 4. A Broad Based Environment for Test (ABBET) with nine active projects; 5. Artificial Intelligence Exchange and Service Tie to All Test Environments (AI-ESTATE) with three active projects; and 6. the Standard for the Management of Test and Maintenance Information (TMIMS).

Throughout the meeting week, the six standards-writing subcommittees plus several administrative subcommittees met daily. Several significant events transpired during the meeting:

tx1800 x8280 § SCC20 held its annual election of officers. Lawrence Carpenter, ARINC, was re-elected as chair and Harry McGuckin, US Navy, and Michael Blair, GEC Feranti, were re-elected as vice chairs.

tx1800 x8280 § Several new participants attended meetings on ATLAS 2000, the next version of the ATLAS language. Progress on ATLAS 2000 included finalization of the language2s functional specification and discussion of a new language architecture document.

tx1800 x8280 § The SCC20 Steering Committee submitted a new PAR to re-establish a project to revise IEEE Std 771 (ATLAS User's Guide). The new PAR was necessary after the withdrawal of the old one at a September Standard's Board meeting, an action that was taken in spite of the fact that a revision of IEEE P771 was undergoing ballot.

tx1800 x8280 § The TEDL committee also suffered withdrawal of their PAR and standard. The revised TEDL standard has completed its balloting process and has passed its ballot as a full-use standard. The revised standard will be forwarded with a new PAR to the Standards Board for approval.

tx1800 x8280 § The ATPG subcommittee approved balloting of the current draft of the DTIF standard. The subcommittee continues to attempt to coordinate with the Computer Society's STIL (Standard Tester Interface Language) standards committee. In addition, the ATPG subcommittee is exploring approaches to standardize analog and mixed-signal test program generation.

tx1800 x8280 § The ABBET subcommittee is currently balloting full-use versions of P1226 (Overview and Architecture), P1226.3 (Resource Management), and P1226.4 (Instrument Drivers). The ballots for P1226 and P1226.4 have been delayed while prototyping and copyright issues are resolved. P1226.3 has completed two ballot circulations and is preparing for a third.

tx1800 x8280 § The AI-ESTATE subcommittee completed balloting on P1232.1 (Data and Knowledge Specification) and are now preparing P1232.2 (Service Specification) for ballot.

tx1800 x8280 § The TMIMS subcommittee, having completed their requirements definition, are drafting the standard. They hope to ballot P1389 in the middle of 1997.

SCC20 is currently examining its scope, vision, and organization. Their goal is to enable more effective and efficient development of test-related standards for the IEEE. Through its Strategic Planning Working Group, SCC20 recognized and endorsed its focus on developing system test standards. As a result, SCC20 will be known as the System Test Standards Committee rather than the ATLAS Committee of old.

The next regularly scheduled meeting of SCC20 will be held in May in Anchorage, Alaska. IEEE members and test professionals are invited to attend and participate. Interested parties should contact the chair of the Meeting Arrangements Subcommittee, Dr. William R. Simpson, at (703) 845-6637 or rsimpson@ida.org.

Are your ATE computers about to bite you?

ATE and the Y2K Problem

If you or your company use or manufacture ATE, you should pay special attention to this article and its references.

Here, in a nutshell, is the Y2K problem: most computer systems in use allow for only two characters for the year date in their system software, as do most, if not all, financial programs on the market today. Often this two-digit number is used in math algorithms, etc.

So what happens when this number goes to 00 for the year 2000? Depending on how your computer and its application programs are designed, the least that can happen is you will get incorrect calculation results. The most drastic thing would be system failure, loss of data and possible financial ruin. In some computer programs, 99 can create a problem because it is recognized as an end-of-file character, aborting programs. In other computers incorrect algorithms have been used to recognize leap- years: the year 2000 is a leap-year, but the year 1900 was not.

So how does all this affect ATE makers and users? In many ways. Unless you have checked every software driver, ATE application program, both home brewed and COTS, and general software used by your ATE computers or those you have shipped, you can not be sure that that they will not stop operating when they start calculating dates in the 2nd millennium.

To fix this could cost you millions of dollars and manpower that you do not have, you say? True, but the sooner you and your company realize the importance of this problem and the sooner you start to develop a plan to address it, the better off you will be.

Apparently Y2K is not just a software problem. IBM, Digital, and others have discovered that they have older mainframes (such as the IBM S/370s) that can not be fixed and have to be replaced (Information Week, 5 Feb2E 1996)!!

You say you are on top of the Y2K problem? Great! But what about other departments in your company? What about the vendors and distributors you deal with? Could a failure of a prime vendor seriously affect your organization?

The Y2K problem has the potential to become a serious financial problem. Your company management needs to put serious effort into a solution before the situation gets out of hand. The federal government has estimated that it will cost billions of dollars to fix this problem at the federal level alone. The issue has already been presented to Congress.

For a great outline of the Y2K problem and some solutions, see the January 1997 issue of Datamation Magazine and the following WWW sites:
