    The design and test of communication protocols relies extensively on formal description languages. In this protocol design and verification scheme, high-level models serve in generating simulation sequences for low-level models, and all simulation is based on directed testing. The methodology is versatile and flexible, and difficult to set up the first time. View full abstract»

    DRAM production tests are currently necessary to reach a defect-per-million level that approaches the single-digit numbers. This implies that a single memory test is insufficient; rather, a set of tests is necessary. This application of 40 well-known memory tests to 1,896 1-Mbyte × 4 DRAM chips, used up to 48 different stress combinations with each test. The results show the importance of se...

    Richard Newton inspired Berkeley’s engineering faculty to come together and envision a way to maximize their collective impact on society. Ken Wagner, IEEE Design & Test's interviews editor, spoke with Newton about the resulting Center for Information Technology Research in the Interest of Society. Newton's view is that the 21st century will be the "century of the engineer." View full abstract»

    The role of standards in EDA has evolved through the years, and it continues to evolve as the industry matures. The EDA industry has existed for only about 25 years. Standards have always benefited users, and EDA standards are no exception. However, in the late 1980s, most EDA vendors viewed standards with some degree of suspicion and trepidation. Many believed that standardization meant lack of d... View full abstract»
