The world of testing is living a big transformation that is sometimes referred to as a “paradigm shift”: traditional structural ATPG is reaching its limit, and functional testing is reclaiming a big role. Unfortunately, current Design-for-Test (DfT) are tailored for structural approaches and are extremely inefficient for functional testing. This demands a complete overhaul not only of the DfT approaches, but also of the EDA tools supporting them. Some advances have been made, most notably by the IEEE 1687-2014 standard which for the first time allows for dynamically-reconfigurable scan chains. IJTAG, as it is also known, also introduces the concept of “instruments”. This solution has a huge potential, but is also a serious impact on current EDA tools and practices. DAUIN already started investigating the issue, noticeably thanks to the participation in the BASTION project.
Michele Portolan is one of the authors of the IEEE 1687-2014 standard, and has been focusing on the EDA side of the problem, noticeably developing the “Manager for SoC Test” (MAST) tool, which implements several innovative abstractions to propose a fully-fledged EDA environment for dynamic and functional testing.
The two efforts are not only complementary, but also coherent. The aim of this collaboration is to leverage the respective strengths and know-how to propose new disruptive solutions in the 1687 space for both testing and functional safety.
