dc.description.abstractIn the aerospace sector, the increasing system complexity of on-board processing for next-gen functionalities (e.g., autonomy) requires high-computational power. This typically leads to advanced cyber (SW and HW) platforms adopting multicores, GPUs, and Artificial Intelligence (AI) accelerators. In this setting, anticipating the integration verification activity earlier in the V development is crucial to save time and costs; and this can be enabled by migrating from real HW prototypes to virtual platforms where the on-board SW applications can run on top of them and fed by real operational data (namely, an as-designed digital twin of the system under test). This capability is among the objectives of the METASAT Horizon Europe project where a Model-Based Engineering approach is developed to build an as-designed digital twin of a high-performance platform coupling an open-source RISC-V GPU with a RISC-V based CPU Instruction Set Simulator (ISS) integrated with an AI accelerator. To build the virtual HW platform of such a digital twin, this paper presents an approach based on open standards (SystemC and TLM 2.0) for the integration of a GPU’s register transfer level (RTL) intellectual property (IP) with an HW platform model. Finally, such an approach has been applied to the METSAT case study.en
