Job Description: The Role: As a CPU Microarchitecture/RTL design engineer at SiFive, you will be part of a team of engineers who are passionate about designing industry-leading CPU cores, based on the revolutionary open-source RISC-V architecture. We are looking for people who are as excited as we are about working in a fast-paced dynamic environment to bring new hardware IP to market quickly, with high quality and exceptional performance. Responsibilities Architect, design and implement new features, performance improvements, and ISA extensions in RISC-V CPU core generators using Chisel. Integrate new design content into SiFive's Chisel/FIRRTL framework and contribute to improvements to that framework to enable automatic configuration/generation of documentation, verification testbenches and tests, and packaged software. Perform initial sandbox verification, and work with the design verification team to create and execute thorough verification test plans. Work with the physical implementation team to implement and optimize physical design to meet frequency, area, and power goals. Collaborate with the performance modeling team for performance exploration and optimization to meet performance goals. Microarchitecture development and specification. Ensure that knowledge is shared via great documentation and participation in a culture of collaborative design. Requirements BS/MS degree in computer science, computer engineering, electrical engineering or related field, or equivalent experience. 5+ years of design experience. Academic or professional experience with CPU RTL design. Proficiency in hardware (RTL) design in Verilog, System Verilog, or VHDL. Strong software engineering skills/background, including: + Object-oriented, aspect-oriented, and particularly functional programming + Templated metaprogramming, in any language + Compiler infrastructures, particularly for domain-specific languages + Data modeling, particularly intermediate representations for optimizing or transforming compiler passes + Test-driven development, particularly ability to write adaptive unit tests Attention to detail and a focus on high-quality design. Ability to work well with others and share the belief that engineering is teamwork. Nice-to-haves Experience with Scala/Chisel, Bluespec, or some other language/DSL for expressing configurable hardware via software. Knowledge of RISC-V architecture. Expertise in CPU processor designs in one or more of the following areas is a plus: instruction decode; register renaming, reorder buffer, and instruction scheduling; vector units; load-store unit. Knowledge of verification principles, testbenches, UVM, and coverage. Experience with Git/Github, Jira, Confluence.
