Full-time

About the Job

Requirements

  • Deep experience verifying high-performance superscalar CPUs, ideally including out-of-order and speculative processors.
  • Strong knowledge of RISC-V architecture, including ISA compliance, privileged architecture, virtual memory, atomics, vector extensions, and memory model behavior.
  • Proficiency in SystemVerilog, UVM, constrained-random verification, assertions, functional coverage, and advanced debug methodologies.
  • Hands-on experience with CPU reference models, instruction generators, instruction-set-simulator-based checking, or differential testing.
  • Practical expertise with formal verification and large-scale CPU verification environments.

Responsibilities

  • Lead verification strategy and execution for next-generation RISC-V high-performance processors.
  • Own verification strategy for RISC-V high-performance superscalar CPUs and CPU subsystems.
  • Drive verification planning for out-of-order, speculative, superscalar microarchitectures.
  • Build and scale test plans, coverage, checkers, assertions, scoreboards, and constrained-random environments.
  • Verify CPU features including frontend, branch prediction, rename, scheduling, execution, load-store, memory ordering, cache hierarchy, retirement, exceptions, interrupts, debug, and coherency interactions.
  • Work closely with architecture, RTL, performance modeling, system-on-chip, firmware, compiler, and validation teams.
  • Establish best practices across the CPU verification organization.
  • Drive verification closure, bug triage, root-cause analysis, coverage closure, and tapeout readiness.
  • Guide verification from early design through tapeout, post-silicon validation, emulation, field-programmable-gate-array prototyping, and silicon bring-up.

Desired Qualifications

  • Experience verifying complex out-of-order, speculative, superscalar CPUs.
  • Experience with RISC-V high-performance processors.
  • Experience with CPU reference models, instruction generators, instruction-set-simulator-based checking, or differential testing.

About the Company
