Book Review H. Y. Chang, E. Manning, G. Met ze Fault Diagnosis of Digital Systems Wiley-lnterscience 1970, 150 pp., $9.50 Beginning with some basic definitions and progressing through the idea of gedanken experiments toward generating tests for sequential logic--the authors lead you on a clearly defined path. The first sections of the book describe the history of test generation and attempt to provide some reasons for considering this problem worthy of solution. From this basic groundwork they then introduce techniques for generating tests. First for combinatorial circuits and then for sequential ones. They also discuss minimization of test patterns and fault simulation. All these topics are presented clearly and with many examples that enable the reader to weigh the relative merits of each algorithm or heuristic. The latter sections of the book discuss the work on the Sequential Analyzer done by Sundrun Seshu. This technique is described in some detail. The book then wraps up with a discussion of fault dictionaries and some speculation as to the future trends of test generation. In general I found this book well written and a welcome addition to mY library. It is valuable both to the novice and the experienced student of test generation who might not be able to understand the original works. It is the aim of the authors not to treat each technique completely but rather to stimulate the reader so that he will delve into the works in their original form. Steve Krosner IBM ACM Charter Flight to Ljubljana Yorktown Heights, N.Y. To service members and their families ACM has arranged for a charter flight to the 5th International Congress of IFIPS, to be held August 23-28, 1971, in Ljubljana, Yugoslavia. The ACM charter flight will depart for Zagreb, Yugoslavia, from Washington, D.C., and/or New York City on August 15, 1971. Zagreb will be the starting point for two different group tours, or for independent travel. Following the congress the ACM charter group will be returned to Zagreb and will depart on August 29, 1971, for home. The round trip fare per person will not exceed $245. Specific information about this charter flight should be requested from: Miss Elaine M. Kokiko Moshman Associateg, Inc. 6400 Goldsboro Rd. Washington, D.C. 20034 Phone (301) 229-3000 -i4-
