1. Introduction The clock frequency of high performance VLSIs has exceeded 2GHz. Over the years, aggressive scaling of CMOS process technology has resulted in a 30% annual performance improvement for digital circuits. However, tester speed has improved by only 12% every year. Figure 1 shows data from the International Technology Roadmap for Semiconductors (ITRS'01) [1], for device under test pe...

This article introduces a novel approach for the integration of JTAG/Boundary Scan tools with other Automated Test Equipment. Previous technologies typically stopped short of being really integrated by just executing the same stand-alone Boundary Scan test vectors on a third party ATE, instead of combining resources of both the JTAG tool set and the third party ATE. HySCAN, the method introduce...

The semiconductor technology development makes it possible to fabricate increasingly advanced integrated circuits (ICs). However, because of imperfections at manufacturing, each individual IC must be tested. A major problem at IC manufacturing test is the increasing test data volume as it leads to high automatic test equipment (ATE) memory requirement, long test application time and low through...

The increasing growth of sub-micron technology has resulted in the difficulty of testing. Design and test engineers have left no choice but to accept new responsibilities that had been performed by group of technicians in the previous years. Design engineers who do not design systems with full testability had increased the possibility of product failures and missed market opportunities. BIST is...

This paper presents a collection procedures to perform interoperability tests of C2X communication equipment. Following a cross layer approach, interoperability test purposes on radiocommunication equipment, networking layer algorithms, C2X applications and use cases are analyzed. Along with this analysis the main conclusions gathered from the execution of the proposed test cases on a concrete ...

Caterpillar has for many years used telemetry as a key component in the data acquisition and analysis systems used to test and develop heavy equipment. The testing of construction and mining equipment at Caterpillar presents several unique challenges, such as the operating environment of the test machine, the large number of models in the product line, the need to change test machines on a dail...

Paraformaldehyde powder, depolymerized by heat, produced formaldehyde gas that was effective in sterilizing laboratory rooms, a mobile laboratory trailer, various surfaces, fiberglass filter medium, and specialized laboratory equipment. A sporulating and nonsporulating strain of bacteria, a virus, and a bacterial toxin were used as test agents. The dissemination procedures and equipment, the as...

Managing a nuclear power plant (NPP) calls for evaluation and trading off the conflicting objectives of safe operation and economic burden. The reduction of NPP risk is strongly correlated to the reduction of NPP safety systems unavailability. The application of the probabilistic safety assessment in order to reduce safety systems unavailability is one of the prime goals in the nuclear safety a...
