Core Responsibilities

Primary Functions

  • Own RTL design and implementation for assigned subsystems using SystemVerilog/Verilog (or VHDL), translating micro-architecture specifications and requirements into synthesizable, timing- and area-efficient RTL code while ensuring testability and reusability.
  • Lead IP integration and subsystem integration activities on SoC projects: adapt third-party and internal IP, define integration interfaces, resolve compatibility and clock/reset domain issues, and ensure successful merge into the top-level design.
  • Execute synthesis flows with commercial EDA tools (e.g., Synopsys DC, Cadence Genus), develop synthesis constraints and scripts, optimize RTL to meet area, power, and timing trade-offs, and iterate with verification and physical design teams.
  • Perform static timing analysis (STA) and timing closure using PrimeTime, Tempus or equivalent: build timing constraints, identify critical paths, propose and implement micro-architecture or physical fixes, and sign off timing at block and chip level.
  • Drive clock tree strategy and clock domain crossing (CDC) design: define clocking architecture, implement CDC synchronization, perform CDC linting and analysis, and collaborate with RTL authors to mitigate metastability risks.
  • Implement low-power design techniques: power domain partitioning, power gating, multi-voltage handling, clock gating, power-aware synthesis, and collaborate on power intent specification (UPF/CPF).
  • Collaborate with verification teams to plan and execute block-level and integration verification: provide testbench hooks, write directed tests, review UVM test plans, and support coverage closure to achieve first-pass silicon quality goals.
  • Define and implement DFT strategy including scan architecture, insertion of scan chains, boundary scan (if required), built-in self-test (BIST) features, prepare for ATPG and production test flow, and work with test/foundry teams to ensure testability.
  • Interface with physical design and P&R teams during floorplanning, pin assignment, and placement iterations: provide constraints, resolve congestion, iterate on macro placement, and support timing closure through RTL changes or engineering fixes.
  • Participate in architecture trade-off discussions that balance performance, power, area, and time-to-market. Provide estimates for area, timing, power, and complexity during design reviews and planning phases.
  • Lead silicon bring-up and post-silicon debug activities: define bring-up test plans, analyze early silicon data (JTAG, scan, logic analyzers), isolate RTL or physical issues, propose silicon fixes, and coordinate ECOs or mask changes as needed.
  • Author and maintain clear technical documentation: micro-architecture specs, RTL coding guidelines, design checklists, synthesis constraints, lint rules, and sign-off reports to support reproducibility and cross-team knowledge transfer.
  • Troubleshoot functional and performance regressions across the design flow: correlate RTL behavior, gate-level simulation, STA reports, and silicon measurements to identify root causes and deliver pragmatic fixes.
  • Develop and maintain automation scripts and flows (TCL, Python, Perl, Shell) to accelerate common tasks such as constraint generation, regression orchestration, report parsing, and data visualization.
  • Engage with EDA tool vendors, IP providers, and foundry contacts to resolve tool issues, optimize flows, and qualify process corners and PVT variations for robust silicon operation.
  • Ensure design-for-manufacturability (DFM) and reliability considerations are addressed: include margins for voltage/temperature, address signal integrity, electromigration concerns, and collaborate on physical verification (DRC/LVS) closure.
  • Conduct design reviews and provide mentorship for junior designers: enforce coding standards, review RTL and test benches, and foster best practices for modular, synthesizable, and maintainable design.
  • Support cross-functional sprint planning and deliverable scheduling: provide realistic development estimates, identify critical path milestones, and communicate dependencies and risks to project stakeholders.
  • Maintain quality and compliance through rigorous linting, formal checks (when applicable), static checks, and design rule adherence; participate in sign-off gate reviews to ensure production readiness.
  • Contribute to IP reuse strategy and productization: refine block APIs, parameterize modules for configurability, provide comprehensive test vectors, and package documentation for future projects.
  • Coordinate with system and firmware teams to validate silicon-hardware interactions: define register maps, bus protocols, interrupt behavior, and support early FPGA-prototyping or emulation where necessary to accelerate software bring-up.
  • Lead reliability and margin analysis including corner-case validation, aging simulations, and stress testing to guarantee product robustness across expected operating conditions.
  • Support cost and yield optimization efforts by proposing RTL or architectural changes that reduce die size, power consumption, or test time without sacrificing functional requirements.

Secondary Functions

  • Support cross-functional root-cause analysis for production issues and coordinate corrective actions with manufacturing, test, and field teams.
  • Contribute to continuous improvement initiatives for the ASIC design flow, including automation of repetitive tasks, tooling standardization, and documentation updates.
  • Participate in vendor and IP qualification activities, reviewing datasheets, release notes, and integration guides to minimize integration risk.
  • Provide on-call support for critical tapeout milestones and early silicon validation to ensure timely delivery and problem resolution.
  • Assist in recruiting, interviewing, and onboarding new ASIC designers; build training materials and run brown-bag sessions to upskill the team.
