ATLANTIC CITY, N.J. -- Advantest Corp., long established in memory testing, is making a big push in logic testing, as it announced new products and partnerships at the International Test Conference here today.
The Japanese company launched a new VLSI test system, the T6682, which is a high-performance version of the 500-MHz T6672 logic test system. Aimed at system-level ASICs and high-speed microprocessors, the T6682 tests devices at 500 MHz to 1 GHz speeds with 1,024 multipins--a proprietary architecture that supports single-wire I/O, split input and output, and fly-by per pin.
The T6682 shares interchangeable hardware fixturing and test programs with the T6672, making the two systems "truly an integrated family," according to Rick Chrusciel, product manager for the T6600 logic test system at Advantest America, based in Santa Clara, Calif. Both systems can be used for characterization and production.
The high-speed pin card design of the T6682 increases its reliability and decreases the overall test station footprint, said Advantest. Pin cards typically have the highest failure rate of any boards in a test system, according to Chrusciel.
"The new pin card electronics solve the two highest failure rate features of treaditional pin cards: the relays and frontend electronics," Chrusciel said. Combining PhotoMOS relays, whih replace mechanical relays, with Advantest's Immersion Cooled Electronics (ICE) increases the mean time between failure of the pin card to above 3,000 hours, even on multi-layered cards that have 64 I/O channels per board.
Through a partnership with Integrated Measurement Systems Inc., Advantest will offer IMS's test-productivity and advanced pattern-generation software on its T6600 logic test family. The combination will save customers time and money in the process of developing IC verification and production test programs, Advantest said.
"We have many customers eagerly waiting to use IMS's Digital VirtualTester and TestDirect software to aid in early test program development and debug for our T6600 systems," Chrusciel said.
Digital VirtualTester uses behavioral simulation technology to verify and debug IC timing test patterns. IMS claims it reduces test debug times during the test development process by as much as 50%. TestDirect is an advanced pattern-generation program that automatically generates test patterns from the original simulation. Advantest will offer the IMS software in the fourth quarter.
"Our partnership will give Advantest customers a strategic advantage by providing them with a design-to-production test software system that will get products to market faster at lower cost," said David Flaningham, general manager of IMS's Virtual Test Division in Beaverton, Ore.
