ICCAD '89 Johnson Chan Limqueco Department of Computer Science University of Illinois at Urbana-Champaign 1304 W. Springfield, Urbana, IL 61801 This year's ICCAD was slightly different from the previous year's. First of all, the tutorials were held on the last day of the conference, instead of the first day. Secondly, presentors of papers in the technical sessions were all required to use slides, instead of having the option of using transparencies. As a result, the technical sessions were better organized, ran more smoothly, and looked more professional, My research work being in Logic Synthesis, the sessions I attended were mostly in this or related areas. One thing that stood out to me from attending all those sessions was the intimate relationship between logic synthesis and testing. Researchers were finding out more and more on how this can be exploited to produce optimal yet testable designs. Hachtel et al., in their paper, "On Properties of Algebraic Transformations and the Multifault Testability of Multilevel Logic," showed that algebraic factorization can be applied to a minimized two-level circuit which is completely single-fault (and therefore, also multifault) testable to produce an area-optimized, completely multifault testable multilevel circuit. Furthermore, all multifault tests of
