Core Responsibilities

Primary Functions

  • Architect and deliver USB controller and PHY-facing IP blocks (Device, Host, OTG, and hub variants) from specification to silicon, ensuring modularity, configurability, and reuse across product lines.
  • Design synthesizable RTL (SystemVerilog/Verilog/VHDL) for USB protocol and controller logic with a focus on timing closure, resource efficiency, and synthesis friendliness for multiple process nodes.
  • Implement and maintain comprehensive UVM/SystemVerilog verification environments, including directed tests, constrained-random tests, functional coverage models, and scoreboard checkers to ensure protocol correctness and regression stability.
  • Develop and execute protocol-level compliance test plans aligned with USB-IF specifications and coordinate formal certification and compliance testing with external test labs.
  • Integrate PHY interfaces (PIPE, ULPI, SERDES lanes for USB3.x/USB4) and manage clock domain crossings, CDC handling, and synchronization between PHY and MAC layers.
  • Lead FPGA prototyping efforts to validate IP functionality and performance on real hardware, enabling early software bring-up and hardware/software integration testing.
  • Perform RTL-level performance optimization and throughput tuning, addressing bottlenecks such as DMA interfaces, endpoint buffering, and bus arbitration to meet product targets for bandwidth and latency.
  • Create and maintain detailed design specifications, architecture documents, micro-architecture descriptions, release notes, and API/driver interface documentation for internal teams and customers.
  • Collaborate with PHY, analog, package, and board teams to define electrical requirements, IBIS models, PHY calibration flows, and signal integrity constraints for high-speed USB implementations.
  • Implement and validate power management features (link power states, LPM, U1/U2/U3, selective suspend), clock gating and low-power modes to meet system power budgets and mobile/embedded use cases.
  • Support silicon bring-up activities: debug RTL-to-silicon issues, analyze hardware logs, collect JTAG/trace outputs, perform logic/analyzer captures and coordinate patch releases or ECOs post-silicon.
  • Lead root-cause analysis of functional failures, propose bug fixes, prepare regression tests for corner cases, and track issue triage across software, firmware and hardware teams.
  • Drive IP quality and security initiatives including static linting, formal verification runs, lint rule enforcement, and adoption of design for testability (DFT) and eBIST features.
  • Mentor junior engineers and verification engineers, conduct design reviews, and enforce best practices for code style, testability, and documentation to improve team productivity and IP reliability.
  • Interface with customers and partners to capture functional requirements, support custom IP configurations, provide technical guidance during integration, and troubleshoot field issues.
  • Maintain and evolve continuous integration (CI) flows for simulation regressions, lint, synthesis checks, and formal runs to accelerate development cycles and ensure repeatable quality metrics.
  • Drive cross-functional feature scoping, roadmap planning and release management for IP deliverables, balancing feature richness, risk, schedule, and reusability.
  • Implement and maintain version control, branching strategies and change management for IP source code, testbenches, and verification assets across distributed teams (Git, Perforce, SVN).
  • Conduct timing closure and static timing analysis (STA) sign-off activities in coordination with physical design and synthesis teams, including constraint creation and multi-corner, multi-mode analysis.
  • Collaborate with driver and firmware teams to define register interfaces, interrupt models, DMA descriptors, and to validate end-to-end software-hardware interactions for device enumeration and class compliance.
  • Develop and run automated regression suites on cloud or local simulation farms and manage test coverage metrics, failure triage workflows and performance dashboards for continuous quality improvement.
  • Evaluate and integrate third-party IP or open-source reference implementations when appropriate, performing security and IP licensing due diligence and harmonizing interfaces.
  • Support field returns and failure analysis by reproducing customer issues in lab, performing protocol traces with USB analyzer tools, and delivering robust fixes or workarounds in both IP and firmware.

Secondary Functions

  • Participate in cross-team planning, sprint reviews and roadmap discussions to align IP features with SoC release schedules and customer milestones.
  • Contribute to process improvement initiatives: improve verification productivity by adopting new UVM utilities, introduce formal property checks, and standardize testbench components.
  • Provide technical input for product datasheets, integration guides and application notes to accelerate customer adoption of the USB IP.
  • Support pre-sales and customer engagements by preparing technical proposals, feasibility studies and demonstrating USB IP performance and capabilities on evaluation boards.
  • Assist in maintaining lab infrastructure: manage FPGA boards, debug tools (oscilloscopes, protocol analyzers), and maintain automated test rigs for validation cycles.
  • Support ad-hoc investigations into performance anomalies, power regressions, or interoperability failures with third-party hubs, host controllers, and operating system stacks.
  • Help translate customer feedback into prioritized bug backlog items and feature requests, working closely with product management to refine release plans.
  • Contribute to knowledge-sharing across the organization through technical talks, documentation updates, and establishing a reusable IP checklist for new projects.
