High-level synthesis (HLS) is increasingly popular for the design of high-performance and energy-efficient heterogeneous systems, shortening time-to-market and addressing today’s system complexity. HLS allows designers to work at a higherlevel of abstraction by using a software program to specify the
hardware functionality. Additionally, HLS is particularly interesting for designing field-programmable gate array circuits, where hardware implementations can be easily refined and replaced in the target device. Recent years have seen much activity in the HLS research community, with a plethora of HLS tool offerings,
from both industry and academia. All these tools may have different input languages, perform different internal optimizations, and produce results of different quality, even for the very same input description. Hence, it is challenging to compare their performance and understand which is the best for the hardware to be implemented. We present a comprehensive analysis
of recent HLS tools, as well as overview the areas of active interest in the HLS research community. We also present a firstpublished methodology to evaluate different HLS tools. We use our methodology to compare one commercial and three academic tools on a common set of C benchmarks, aiming at performing
an in-depth evaluation in terms of performance and the use of resources.@en

The complexity of the health care environments necessitates an holistic and systematic ergonomics approach to understand the potential for accidents and errors to occur. The health service is also a socio-technical system, and design needs must be met within this context. This paper aims to present the design challenges and emphasises the specialised needs of the health care sector, when dealing with patient safety. It also provides examples of approaches and methods that ergonomists can bring to help inform our knowledge of these systems and the potential towards improving their safety. Mapping workshops provide an example of such methods. Results from these are used to illustrate how the knowledge base required for better design requirements can be generated. The workshops were developed specifically to help improve the design of medication packaging and thereby reduce the probability of medication error. The issues raised are now the subject of further research, design requirements guidance and new design concepts. The paper illustrates the need to engage with the design community and, through the use of robust scientific methods, to generate appropriate design requirements.@en
