Biographical sketches of authors

William V. Huott IBM System/390 Division, 522 South Road, Poughkeepsie, New York 12601 (ace@vnet.ibm.com). Mr. Huott is an Advisory Engineer in S/390 custom microprocessor design. He received a B.S. in electrical engineering from Syracuse University in 1984. Mr. Huott is a design engineer responsible for the definition and design of the memory array built-in self-test (ABIST) circuitry and interfaces for high-frequency custom microprocessors. He is also responsible for the engineering test debug of high-frequency custom macros and support chips. Mr. Huott joined IBM in 1983 at the East Fishkill facility designing, testing, and debugging high-speed logic gate arrays and memory arrays. He holds four U.S. patents and several publications.

Timothy J. Koprowski IBM System/390 Division, 522 South Road, Poughkeepsie, New York 12601 (tkoprowski@vnet. ibm.com). Mr. Koprowski is an Advisory Engineer in S/390 custom microprocessor design. He received his B.S. in electrical engineering from Lehigh University in 1981 and is currently pursuing an M.S. degree in computer engineering at National Technological University. He is a design engineer responsible for the definition and design of the LBIST circuitry for high-frequency custom microprocessors. Mr. Koprowski joined IBM in 1981 at the East Fishkill facility, where he designed advanced VLSI logic and memory test systems for eleven years. He holds one U.S. patent.

Bryan J. Robbins IBM System/390 Division, 522 South Road, Poughkeepsie, New York 12601 (brobbins@vnet. ibm.com). Mr. Robbins received the B.S. degree in electrical engineering from Purdue University in 1986, and the M.S. degree in computer and electrical engineering from Purdue University in 1988. He is an Advisory Engineer responsible for test modeling and test generation for high-frequency custom microprocessors. Mr. Robbins joined IBM in 1988 at Poughkeepsie, New York.

Mary P. Kusko IBM Microelectronics Division, East Fishkill facility, Route 52, Hopewell Junction, New York 12533 (mkusko@vnet.ibm.com). Ms. Kusko is an Advisory Engineer in EDA (electronic design automation). She received a B.S. in electrical engineering from the University of Delaware in 1982, joining the IBM S/390 Division that same year. From 1982 to 1993 she held several positions in processor design. Since 1993, she has worked in the areas of test strategy definition and implementation, model generation, test analysis, test generation, and internal test tool direction. Ms. Kusko is a member of the IEEE, SWE, and TTTC.

Stephen V. Pateras LogicVision Inc., 101 Metro Drive, Third Floor, San Jose, California 95110 (pateras@lvision.com). Dr. Pateras received his Ph.D. degree in electrical engineering from McGill University in 1991. While at IBM, he served as test team leader in the S/390 custom microprocessor group. He is now Director of System BIST Product Engineering at LogicVision. Dr. Pateras is a member of the IEEE and has authored or coauthored several papers and articles in the fields of test generation and BIST.

Dale E. Hoffman IBM System/390 Division, 522 South Road, Poughkeepsie, New York 12601 (daleh@vnet.ibm.com). Mr. Hoffman received a B.S. in electrical engineering from Pennsylvania State University in 1981, and an M.S. in electrical engineering from Syracuse University in 1984; he is currently pursuing an M.S. in computer engineering at National Technological University. He is a Senior Engineer and a design manager responsible for test, chip integration, physical design, and back-end design methodology for high-frequency custom microprocessors. Mr. Hoffman joined IBM in 1981 at the East Fishkill facility, where he designed and managed advanced VLSI logic and memory test systems for eleven years. He holds five U.S. patents and has several publications.

Timothy G. McNamara IBM System/390 Division, 522 South Road, Poughkeepsie, New York 12601 (tmcnamera@vnet.ibm.com). Mr. McNamara is an Advisory Engineer in S/390 custom microprocessor design. He received his B.E. in electrical engineering from the State University of New York at Stony Brook in 1983 and his M.S. in computer engineering from Syracuse University in 1990. He is currently working on high-performance clock system designs for S/390 CMOS microprocessors. Mr. McNamara holds two U.S. patents.

Tom J. Snethen IBM Microelectronics Division, 1701 North Street, Endicott, New York 13760 (snethent@endvm5.vnet. ibm.com). Mr. Snethen is a Senior Engineer in the IBM Test Design Automation project. He received the B.S.E.E. degree from the University of Missouri and the M.S.E.E. from MIT before joining IBM in 1965. Mr. Snethen is a member of the IEEE. He holds one patent and has authored or coauthored several papers in the field of fault modeling and test generation.
