Job Description:
Summary
As a Senior Staff Hardware Engineer in Design Verification, you will own verification strategy and execution for complex SoC / IP blocks, driving quality from architecture through tape‑out. You will define methodology, lead test plan creation, guide junior engineers, and be a key technical partner to architecture, design, and validation teams.
Key Responsibilities
- Verification Ownership
- Own verification for one or more complex subsystems (CPU/LSU/cache/interconnect/IP blocks).
- Define verification strategy, methodology, and test plans from spec/architecture documents.
- Ensure coverage closure (functional, code, assertion, and scenario coverage) to sign‑off criteria.
- Testbench Architecture & Implementation
- Architect and implement constrained‑random, coverage‑driven testbenches (System Verilog/UVM or equivalent).
- Develop reusable verification components: agents, monitors, scoreboards, checkers, and VIP integrations.
- Drive block‑level and subsystem‑level test environments, including stimulus generation and self‑checking.
- Formal & Assertion‑based Verification
- Specify and implement assertion sets (SVA or similar) for critical micro‑architectural properties.
- Apply formal verification on key blocks (protocols, arbiter, FIFOs, control logic) to complement simulation.
- Debug & Quality
- Lead bring‑up and debug of complex failures (functional, performance, corner‑case, and silicon escapes).
- Work closely with RTL designers to root‑cause bugs and propose fixes or micro‑architectural clarifications.
- Define and track verification metrics; report status, risks, and mitigation plans.
- Methodology & Infrastructure
- Define and evolve DV methodology (UVM usage, regression strategy, coverage methodology, reuse across projects).
- Collaborate with CAD/infra teams to improve regressions, farm utilization, CI pipelines, and debug flows.
- Introduce and evaluate new tools/flows (formal, lint, CDC, low‑power, emulation/FPGA prototyping).
- Technical Leadership & Mentoring
- Provide technical leadership to DV teams across projects; act as a subject‑matter expert for key IP/flows.
- Mentor junior and mid‑level DV engineers in testbench design, debugging, methodology, and best practices.
- Review and sign off on test plans, environments, and coverage for other team members.
- Cross‑functional Collaboration
- Partner with architects and RTL designers to refine micro‑architecture for verifiability and testability.
- Coordinate with software, validation, and post‑silicon teams to ensure end‑to‑end coverage of use‑cases.
- Participate in spec reviews, micro‑architecture reviews, and tape‑out sign‑off reviews.
Required Qualifications
- Education / Experience
- BS/MS/PhD in Electrical Engineering, Computer Engineering, or related field.
- Typically 10+ years of experience in ASIC/SoC/IP design verification, with demonstrated senior/staff‑level impact.
- Technical Skills
- Strong expertise in SystemVerilog and UVM (or comparable class‑based verification methodologies).
- Proven experience verifying complex CPU/SoC/IP blocks (e.g., cache/memory subsystem, interconnect, accelerators, IO).
- Solid understanding of digital design concepts: pipelines, coherency, memory hierarchy, clocking, resets, CDC.
- Hands‑on experience with:
- Functional and code coverage, coverage‑driven verification.
- Assertion‑based verification (SVA).
- Debug tools (e.g., Verdi, DVE, SimVision) and waveform‑based debug.
- Experience with industry‑standard simulators (VCS, Xcelium, Questa, etc.) and regression infrastructure.
- Domain Knowledge
- Good understanding of one or more: CPU microarchitecture (e.g. RISC‑V/ARM/x86), cache coherence, memory protocols, on‑chip interconnects, or high‑speed interfaces.
- Familiarity with standard on‑chip/off‑chip protocols (e.g. AXI, TileLink).
- Soft Skills
- Strong analytical and problem‑solving skills; able to drive issues from ambiguity to closure.
- Excellent written and verbal communication; comfortable presenting technical topics and status to broader teams.
- Demonstrated ability to lead technically across functions and to mentor other engineers.
