Rapid increases in chip complexity, increasingly faster clocks, and the proliferation of portable devices have combined to make power dissipation an important design parameter. The power consumption of a digital system determines its heat dissipation as well as battery life. For some systems, power has become the most critical design constraint. Computer-Aided Design Techniques for Low Power Sequential Logic Circuits presents a methodology for low power design. The authors first present a survey of techniques for estimating the average power dissipation of a logic circuit. At the logic level, power dissipation is directly related to average switching activity. A symbolic simulation method that accurately computes the average switching activity in logic circuits is then described. This method is extended to handle sequential logic circuits by modeling correlation in time and by calculating the probabilities of present state lines. Computer-Aided Design Techniques for Low Power Sequential Logic Circuits then presents a survey of methods to optimize logic circuits for low power dissipation which target reduced switching activity. A method to retime a sequential logic circuit where registers are repositioned such that the overall glitching in the circuit is minimized is also described. The authors then detail a powerful optimization method that is based on selectively precomputing the output logic values of a circuit one clock cycle before they are required, and using the precomputed value to reduce internal switching activity in the succeeding clock cycle. Presented next is a survey of methods that reduce switching activity in circuits described at the register-transfer and behavioral levels. Also described is a scheduling algorithm that reduces power dissipation by maximising the inactivity period of the modules in a given circuit. Computer-Aided Design Techniques for Low Power Sequential Logic Circuits concludes with a summary and directions for future research.

Welcome to the proceedings of PATMOS 2008, the 18th in a series of int- national workshops. PATMOS 2008 was organized by INESC-ID / IST - TU Lisbon, Portugal, with sponsorship by Cadence, IBM, Chipidea, and Tecmic, and technical co-sponsorship by the IEEE. Over the years, PATMOS has evolved into an important European event, where researchers from both industry and academia discuss and investigate the emerging challenges in future and contemporary applications, design meth- ologies, and tools required for the development of the upcoming generations of integrated circuits and systems. The technical program of PATMOS 2008 c- tained state-of-the-art technical contributions, three invited talks, and a special session on recon?gurable architectures. The technical program focused on t- ing, performance and power consumption, as well as architectural aspects with particular emphasis on modeling, design, characterization, analysis and op- mization in the nanometer era. The Technical Program Committee, with the assistance of additional expert reviewers, selected the 41 papers presented at PATMOS. The papers were - ganized into 7 oral sessions (with a total of 31 papers) and 2 poster sessions (with a total of 10 papers). As is customary for the PATMOS workshops, full papers were required for review, and a minimum of three reviews were received per manuscript.
