Staff RTL Design Engineer - CPU LS/PF/MMU

About 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-standard 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.
• 3+ 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
• Test-driven development, particularly ability to write adaptive unit tests
• Attention to detail and a focus on high-quality design. Good verification principles, SVA, and coverage.
• Ability to work well with others and share the belief that engineering is teamwork.
• Experience with Scala/Chisel, Bluespec, or some other language/DSL for generating configurable hardware via software.
• Knowledge of RISC-V instruction set architecture.
• Expertise in out-of-order processor micro-architecture, design, and verification in one or more of the following areas: load-store unit, coherent caches, cache prefetching, virtual memory MMU/TLBs.
• Familiarity with Git/Github, Jira, Confluence.
• Pay & Benefits
• Base Pay Range
• $178,848.00-$218,592.00
• In addition to base pay, this role may be eligible for variable/ incentive compensation and/ or equity. In addition, this role is eligible for a comprehensive, competitive benefits package which may include healthcare and retirement plans, paid time off, and more!
