Platform optimizes use of DFT and BIST while lowering test costs
Pleasanton, CA, September 20, 2002 -- Inovys Corporation today announced the introduction and immediate availability of the Ocelot, a new DFT test system. The Ocelot has been specifically developed to support the economical testing of the full spectrum of integrated circuits, from low cost consumer devices to the most complex SoCs and microprocessors.
By taking advantage of on-chip test structures such as scan and BIST, the Ocelot tester reverses the trend requiring increasingly expensive ATE systems to test the most complex chips. With up to 1,536 signal pins, the Ocelot can be used to test high I/O SoC devices, or to test more than 32 devices in parallel. With its innovative Dynamic Data Matrix, the Ocelot provides the extended pattern depth and configuration flexibility required for large SoC designs without the high costs associated with large pattern memories. While providing scan data rates up to 50MHz, the Ocelot also offers special highly accurate clock pins that can support AC-scan strategies for at-speed testing of internal signal paths.
The Ocelot runs under Stylus, Inovys' innovative new software operating system that utilizes the IEEE1450 Standard Test Interface Language (STIL) as its programming language. Stylus is a major breakthrough for the design-to-test bottleneck. It links directly to the output of all major commercial ATPG products using the STIL test language. Another major benefit is the ability to link failure information directly back from the Ocelot to the ATPG diagnostic tools for gate level diagnosis of device defects. Since STIL is the native language to the Stylus OS , transfers of data from functional simulators and automatic test pattern generation programs are directly accepted without intermediate translation using third-party tools outside the normal design-to-test flow.
"This is the first in a series of products that answers the semiconductor industry's demand for a new cost/performance breakthrough in component test,", said Paul Sakamoto, CEO of Inovys. "While others have spent a lot of time and money developing cheaper versions of existing architectures, Inovys has taken advantage of the inflection point in the commercial success of DFT, BIST and the EDA tools that support them. By taking careful aim at the whole process of semiconductor design, validation, and test, Inovys engineers and scientists have produced a complete solution that is ten times more productive in terms of development time and cost of ownership. In addition, the resulting test methodology builds on many years of scan and BIST industry research to provide much better fault coverage than any other method."
The Inovys Ocelot test system is available in three configurations -- 512 pins, 1024 pins, and 1536 pins. It offers a wide variety and large number of power supply options to support a broad range of device types, as well as support of multi-site testing.
The most significant benefits to customers using Ocelot test solutions are lower testing costs, quicker test development efforts, and rapid feedback to design teams. With industry leading solutions for larger volume scan patterns, delay fault testing, BIST, and embedded memory, Inovys' innovative test systems address the test challenges of SoC, ASIC, datacomm, DSP, microprocessor, microcontroller, and other complex devices.
Ocelot shipments began in the second quarter of 2002. Pricing for the Ocelot is in the $300,000 to $600,000 range, depending upon pin count and options.
