Integrated Synthesis Methodology for Crossbar Arrays
Nano-crossbar arrays have emerged as area and power efficient
structures with an aim of achieving high performance computing
beyond the limits of current CMOS. Due to the stochastic nature
of nano-fabrication, nano arrays show different properties both
in structural and physical device levels compared to conventional
technologies. Mentioned factors introduce random characteristics
that need to be carefully considered by synthesis process. For instance, a competent synthesis methodology must consider basic
technology preference for switching elements, defect or fault rates
of the given nano switching array and the variation values as well
as their effects on performance metrics including power, delay, and
area. Presented synthesis methodology in this study comprehensively covers the all specified factors and provides optimization
algorithms for each step of the process.This work is part of a project that has received funding from the
European Union’s H2020 research and innovation programme under the

Neuromorphic Computing - From Robust Hardware Architectures to Testing Strategies
International audienceThis paper provides an overview of the challenges faced by hardware implemented Spiking Neural Networks, from device to circuit design, reliability and test. We present a comprehensive description of the state-of-the-art neuromorphic architectures inspired by brain computation, with special emphasis on Spiking Neural Networks (SNNs), together with emerging technologies that have enabled such systems, namely Phase Change and Metal Oxide Resistive Memories. Finally, we discuss the main challenges faced by hardware implementations of SNNs, their reliability and post-fabrication test issues
NEUROPULS: NEUROmorphic energy-efficient secure accelerators based on Phase change materials aUgmented siLicon photonicS
This special session paper introduces the Horizon Europe NEUROPULS project,
which targets the development of secure and energy-efficient RISC-V interfaced
neuromorphic accelerators using augmented silicon photonics technology. Our
approach aims to develop an augmented silicon photonics platform, an
FPGA-powered RISC-V-connected computing platform, and a complete simulation
platform to demonstrate the neuromorphic accelerator capabilities. In
particular, their main advantages and limitations will be addressed concerning
the underpinning technology for each platform. Then, we will discuss three
targeted use cases for edge-computing applications: Global National Satellite
System (GNSS) anti-jamming, autonomous driving, and anomaly detection in edge
devices. Finally, we will address the reliability and security aspects of the
stand-alone accelerator implementation and the project use cases.Comment: 10 pages, 2 figures, conferenc
