The IEEE European Test Symposium (ETS) is Europe’s premier forum dedicated to presenting and discussing scientific results, emerging ideas, applications, hot topics and new trends in the area of electronic-based circuits and system testing, reliability, security and validation. In 2020, ETS will take place in the Radisson Blu Sky Hotel in Tallinn. The city is known for the picturesque Old Town with its medieval architecture. It is organized by the Tallinn University of Technology (TalTech), which co-sponsors the event jointly with the IEEE Council on Electronic Design Automation (CEDA). In addition to scientific paper submissions, ETS offers a track for informal contributions dedicated to early hot ideas and relevant case studies as well as a PhD forum. A Test Spring School and Fringe Workshops will be organized in conjunction with ETS’20.
