Collaboration:
ARTEMIS
To address these challenges, we have developed scalable simulation tools to enable leadership computing systems to model emerging post-CMOS microelectronic devices (electronic, spintronic, nanomagnetic and nanomechanical). Our exascale, open-source code, ARTEMIS (Adaptive mesh Refinement Time-domain ElectrodynaMIcs Solver), contains support for heterogeneous physical coupling. It is portable and scales well on many-core/GPU-based supercomputers that are far beyond the reach of commercial tools, allowing us to capture larger-scale spatial disparities inherent to realistic circuits. We have demonstrated algorithmic flexibility by developing a micromagnetics module. Our current efforts include upgrading the functionality of ARTEMIS to accurately describe new devices such as a magnetoelectric spin-orbit logic, enabling ARTEMIS to serve as the device-level design and optimization tool.
