Responsibilities

Functional and performance verification of the Fabric unit for a from-scratch high performance CPU while working closely with Architecture and RTL team
Develop detailed block level verification plans for a high-performance Fabric Design and develop reusable block level testbench components in SV, UVM and C++, that include microarchitectural models, monitors, checkers
Develop random and directed stimulus that spans pre-silicon, emulation and post-silicon domain
Evaluate and integrate open-source toolchains into the DV flow
Develop DV environment, tools and infrastructure to enable functional verification for pre-silicon, emulation and post-silicon
Work with design, test and post silicon validation teams to ensure high quality delivery of the Fabric / Mem Subsystem block

Tenstorrent is leading the industry on cutting-edge AI technology, revolutionizing performance expectations, ease of use, and cost efficiency. With AI redefining the computing paradigm, solutions must evolve to unify innovations in software models, compilers, platforms, networking, and semiconductors. Our diverse team of technologists have developed a high performance RISC-V CPU from scratch, and share a passion for AI and a deep desire to build the best AI platform possible. We value collaboration, curiosity, and a commitment to solving hard problems. We are growing our team and looking for contributors of all seniorities.
