Job Description:

SiFive is seeking a hardware design technical lead who is passionate about designing industry-leading debug, trace and profiling IP to help drive the tidal wave of adoption of RISC-V as the architecture of choice for SOC designs across a broad variety of vertical applications. We’re creating a highly customizable line of processor cores with fast time-to-market by designing the hardware as highly configurable generators. We're leveraging technology and ideas from the software industry to execute hardware design with the speed and agility of software development. This role focused on debug, trace and profiling will be especially vital to SiFive’s effort to create silicon at the speed of software across our entire IP portfolio, including Essential, Intelligence, Performance, and Automotive product lines.

We build and maintain our RISC-V processor subsystem IP using the Chisel hardware construction library embedded in the Scala language, and are seeking a motivated individual to lead enhancement of our existing debug/trace/profiling hardware as well as development of new capabilities in this area. Additionally, there are opportunities to engage with customer, partners and tools vendors to help determine the future of the debug, trace and profiling solutions, as well as opportunities to engage with the RISC-V International Association to help drive the state of the art of debug strategy.

The successful applicant will address the following challenges:

• Designing the best debug, trace and profiling hardware in the world, based on the revolutionary open RISC-V and TileLink architectures.
• Mastering the art of designing hardware as configurable generators in a domain-specific software language for elaborating digital logic.
• Working in a fast-paced dynamic environment to bring new hardware IP to market quickly, with high quality and exceptional performance.

Join us, and surf the RISC-V wave with SiFive!

Job Responsibilities:

• Architect, design and implement debug, trace and profiling hardware.
• Work with architecture, performance, software and hardware teams in architecture/microarchitecture exploration and specification.
• Implement RTL generators such that elements self-configure to optimally design-in extensive configurability as a first-class consideration.
• 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 design verification team to create and execute thorough verification test plans.
• Ensure that knowledge is shared via creation and maintenance of great documentation and participation in a culture of collaborative design

Position Requirements:

• Knowledgeable in debug, trace and profiling architecture and concepts.
• Knowledgeable in debug interfaces, JTAG, cJTAG.
• Knowledgeable in CPU architectures, power management and SoC design.
• Experience in debugging tools, profiling methods.
• Proficiency with hardware (RTL) design in Verilog, System Verilog, or VHDL.
• Attention to detail and a focus on high-quality design.
• Ability to work well with others and a belief that engineering is a team sport.
• Knowledge of at least one object-oriented and/or functional programming language.
• Knowledge of one or more of: Chisel/Scala, RISC-V architecture, Git/Jira/Confluence is a plus.
• 7+ years of industry experience leading and directly contributing to architecture, microarchitecture and RTL design for debug/trace/profiling hardware for high-performance processors.
• MS/PhD in EE, CE, CS or a related technical discipline.
