SPIL Orders Multiple Tiger Systems for Graphics Processor and Chipset Production; Tiger's Flexible Configurations and High Throughput Deliver Winning Economics

BOSTON--(BUSINESS WIRE)--April 14, 2003--Teradyne, Inc. (NYSE:TER) announced today that Siliconware Precision Industries Co., Ltd. (NASDAQ: SPIL), a leading global IC packaging and testing group, has purchased multiple Tiger systems further expanding their Tiger installed base for production test of Graphics Processors and Chipsets. Subcontractors like SPIL are standardizing on Tiger because its comprehensive Digital and Analog instrument suite, integrated in a 3rd generation SOC architecture, flexibly delivers the performance, throughput and yield required for the full spectrum of computing devices. With Tiger, SPIL can provide highly efficient test solutions for a wide range of Fabless designers and IDMs, all on a single test platform.

"Interface technologies and data rates on Graphics and Chipset devices continue to escalate," commented Bough Lin, Chairman, Siliconware Precision Industries Co., Ltd. "Proven test solutions that minimize test time and reduce time to market are needed for new HyperTransport™ and PCI Express test applications. Teradyne's expertise in HyperTransport and SerDes, coupled with their wide acceptance among Fabless designers, enables SPIL to deliver a highly reliable solution to a broad set of customers."

Tiger's unique Real I/O™ Dual Asynchronous Pattern Generators, using silicon germanium technology, deliver full I/O switching for high speed I/O buses at up to 1.6Gbps enabling high throughput test of next generation high-performance graphics processors and chipsets. All the I/O waveforms required to fully test the part can be generated in a single pattern burst. Waveforms do not have to be reloaded and patterns do not have to be rerun, reducing test time. Critical "data eye" measurements for high-speed interfaces such as TMDS are done in a single pattern pass. Teradyne's Tiger enables test time advantages of over 20-30%, versus other ATE systems without this timing flexibility, and with the availability of these high-speed test features, program development times are reduced from months to weeks.

Tiger's TwinMode™ pin electronics architecture delivers full functional test capability (including single ended, differential, and common mode drive and compare) on any pin. This configuration flexibility makes it easier to test emerging devices that include multiple high-speed interface standards.

"HyperTransport, 1Gbps DDR I/O, and high speed Serial interfaces like S-ATA and PCI Express are rapidly being integrated onto high performance digital parts. We are pleased to provide subcontractors, like SPIL, the advantage of a flexible test suite that minimizes the total number of channel cards, matches tester performance and cost to the needs of the device, and provides comprehensive testing of all device specifications in a single insertion," said Glenn Farris, Product Marketing Manager, Teradyne. "In addition, we are pleased to provide extensive system and program support ensuring SPIL's success with Tiger," concluded Michael Wu, Sales Account Manager, Teradyne.
