“…This enables for example to skip the boot process of an operating system by using a fast simulation technique and focus on the actual application using a more accurate technique. To boost the simulation performance we investigated justin-time compilation techniques in this runtime adaptive setting [74].…”

Virtual prototypes (VPs) are crucial in today’s design flow. VPs are predominantly created in SystemC transaction-level modeling (TLM) and are leveraged for early software development and other system-level use cases. Recently, virtual prototyping has been introduced for the emerging RISC-V instruction set architecture (ISA) and become an important piece of the growing RISC-V ecosystem. In this paper, we present enhanced virtual prototyping solutions tailored for RISC-V. The foundation is an advanced open source RISC-V VP implemented in SystemC TLM and designed as a configurable and extensible platform. It scales from small bare-metal systems to large multi-core systems that run applications on top of the Linux operating system. Based on the RISC-V VP, this paper also discusses advanced VP-based verification approaches and open challenges. In combination, we provide for the first time an integrated and unified overview and perspective on advanced virtual prototyping for RISC-V.
