Risc-v Cpu Microarchitecture / Rtl

Tenstorrent · Semiconductors · Austin, TX · CPU

Tenstorrent is seeking a RISC-V CPU Microarchitecture/RTL owner to develop next-generation CPU designs. This role involves defining microarchitecture specifications, designing RTL, and performing unit verification for CPU components like branch predictors and vector execution units. The candidate will also use AI tools to accelerate the design process and potentially mentor junior engineers. Experience with high-performance CPU RTL design for architectures like x86, Arm, or RISC-V is required.

What you'd actually do

  1. RISC-V CPU Unit Microarchitecture Specification: Define and develop microarchitecture specifications for the assigned unit (branch predictor, rename, instruction scheduling, vector execution, load/store, vector load/store support). The specification includes not only design, but also comprehensive analysis / strategy for verification and PPA (power, performance, area) closure.
  2. RISC-V CPU Core Unit RTL Design: The candidate will be responsible for the quality of RTL including design verification and PPA closure. This includes writing RTL, reviewing / refining unit verification environment, applying right RTL optimization to control PPA.
  3. AI Assisted Design Adaption: To maximize the team’s output, the candidate actively uses AI tools to accelerate the CPU design process.
  4. Mentoring Junior Engineers: depending on a seniority of the engineer, the engineer may mentor junior members in the team.

Skills

Required

  • Bachelor's, Master's, or PhD in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
  • Proven track record of designing high-performance CPU RTL for x86, Arm, POWER, SPARC, or RISC-V.
  • Deep understanding of design verification strategy and trade-offs for verification methodology (simulation, formal, various checkers, etc…)
  • Deep understanding of CPU microarchitecture and PPA trade-off.
  • Proficiency in hardware description languages (HDLs) such as Verilog, SystemVerilog or VHDL.
  • Excellent problem-solving abilities and analytical skills.
  • Strong communication skills, with the ability to convey complex technical concepts to diverse audiences.
  • Ability to work collaboratively in a team-oriented environment and across multiple disciplines.

Nice to have
