CPU Core Feature Verification and Debug Engineer

We are looking for a CPU core level feature / testplan verification engineer responsible for ISA and microarchitectural verification.

This role is hybrid, based out of Austin, TX or Santa Clara, CA.

We welcome candidates at various experience levels for this role. During the interview process, candidates will be assessed for the appropriate level, and offers will align with that level, which may differ from the one in this posting.

Responsibilities:

• Functional verification with emphasis on core level testplanning, stimulus development and regression debug for simulation and emulation regressions
• Understand ISA and microarchitectural specifications for the Core and create comprehensive testplans
• Hands-on debug for core level failures. Propose and implement stimulus enhancements and debug capability improvements for core, cluster and chip level testbench environments
• Develop architectural and microarchitectural coverage for core features and create stimulus for closing coverage in a timely manner
• Support design deployment across simulation and emulation platforms
• Develop random and directed stimulus that spans pre-silicon, emulation and post-silicon domain
• Work with design, test and post silicon validation teams to ensure high quality delivery of the entire CPU core / cluster

Experience & Qualifications:

• BS/MS/PhD in EE/ECE/CE/CS with at least 3 years of experience
• Strong background and experience with high performance OOO CPU microarchitecture
• Experience and understanding of one or more ISAs - x86, ARM or RISCV
• Experience debugging RTL and DV in a simulation environment, proficient at waveform and log file based debug
• Experienced with assembly, C/C++ and UVM based stimulus generation targeting both ISA and microarchitectural scenarios
• Familiar with simulation, formal and emulation environments
• Hands-on with scripting (Python, PERL)
• Experience with hardware description languages (Verilog, VHDL) and simulators (VCS, NC, Verilator)
• Strong problem solving and debug skills across various levels of design hierarchies
