Over the past nineteen years, the IEEE Workshop on Signal and Power Integrity (SPI) has evolved into a forum of exchange on the latest research and developments on design, characterization, modeling, simulation and testing for Signal and Power Integrity at chip, package, board and system level. The workshop brings together developers and researchers from industry and academia in order to encourage cooperation. In view of last years success, the Committee is looking forward to the 20th Edition which will convene in Turin, Italy. The SPI 2016 technical program will include both oral and poster sessions. A number of prominent experts will be giving tutorials on areas of emerging interest. The Conference Proceedings will be published with an ISBN code and will appear in IEEE Xplore.
