Mixed Reality (MR) is closing the gap between real and digital and is changing how we interact with digital content. Making physical objects a part of the user interface creates a direct mapping between virtual and reality and along with that emerges many design benefits. Current head-worn see through Augmented Reality (AR) headsets are not only capable of delivering a MR experience but are also s

There are many advantages with the development towards Integrated Circuits (ICs) with smaller, faster, and more transistors. However, tighter margins lead to a need of on-chip instruments to test, tune, and configure.
