This book brings together the very many interlocking aspects of custom microelectronics, from fabrication technologies through to design and test, in a comprehensive and authoritative manner. Key Features include fabrication details of silicon and GaAs technologies, and circuit details of logic families; comprehensive survey and comparison of the types of integrated circuits available to equipment designers, including standard parts, gate arrays, standard cells, full-custom, one-time-programmable and re-programmable devices; computer aided design tools for custom design, including HDLs, simulation, place and route, design-rule checking and electrical-rule checking; analogue and mixed analogue/digital products and their use; packing for custom integrated circuits; fast prototyping and direct-write-on-wafer; in-depth treatment of design-for-test, including BIST, BILBO, CALBO, boundary scan, and other techniques; and managerial aspects, including design choices, non-recurring-engineering (NRE) costs, second sourcing and legal ownership. Custom VLSI Microelectronics is intended for use both in industry and academic institutions. The book will give design engineers and technical managers a broad coverage of all the details with which they should be familiar when Custom Microelectronics is being considered. Students will find the book an invaluable source of information covering the fundamentals of Microelectronics and computer-aided design.
