Abstract: 

Today¡¯s complex processor-based systems enable technological advances in many market segments, such as AI, high performance computing, and automotive. However, verification of these systems introduces new challenges, spanning architectural verification of a custom RISC-V processor to memory coherency in a system containing thousands of Arm or RISC-V cores. As the complexity of the design increases, so does the need for new tools and methods beyond simulation and UVM testbenches. ?

In this tutorial, we will focus on RISC-V processors and present next-generation verification techniques that span the verification journey from a single RISC-V processor to complex systems with many RISC-V cores. ?

To accommodate the flexible and evolving nature of the RISC-V ISA, as well as privilege mode features, out-of-order pipelines, interrupts and debug mode, RISC-V processor verification requires innovation in stimulus generation, comparison, and checking. We will cover dynamic and formal approaches to verifying RISC-V cores, with topics including, but not limited to: ISA compliance verification and functional coverage, datapath validation, functional verification of critical blocks, and security verification. ?

Multi-core designs introduce a new set of challenges, such as ensuring fair access to shared resources and cache and memory coherence. This tutorial will present solutions designed to address these issues and prevent costly bug escapes to silicon. ?

The size of multi-core designs and multi-processor SoCs means that a simulation-only verification strategy is impractical. Hardware-assisted verification becomes essential to ensuring correct operation in the multi-core designs of today and the future. This tutorial will demonstrate how ÁùºÏ²ÊÖ±²¥¿ª½±¡¯ next-generation processor verification tools and techniques combine with HAV platforms to create a powerful and effective solution. ?

Whether you are designers or verification engineers of these complex processor-based systems, you will walk away with new ideas on how to improve your verification flow by embracing some of these next generation solutions.
