The ACM sponsored TAU series of workshops provide an informal forum for practitioners and researchers working on temporal aspects of digital systems to disseminate early work and engage in a free discussion of ideas. The twenty-seventh in the TAU series, and on its 31st anniversary, the TAU 2021 workshop emphasizes novel aspects of timing and power analysis as well as optimization with special invited talks.

Due to the ongoing and unpredictable nature of the COVID-19 pandemic, the TAU 2021 workshop will be held online.
