About the role

SoC Power Integrity Engineer responsible for development, implementation, and verification of power integrity solutions for Apple SoCs, coordinating with cross-functional teams to define PDN architectures, model and simulate power delivery from die to board, and perform lab validation.

Responsibilities

  • Definition of the PDN architecture and design solution space for systems across a wide range of power specifications.
  • Power delivery modeling, simulation, and characterization for die, interposer, package, board, and Voltage Regulator.
  • Close collaboration with multi-functional teams to design end-to-end power delivery systems for both current and future generations.
  • Broad responsibility on all SoC droop related topics, including on-die inrush, off-die droop budget, PDN signoffs, noise coupling analysis, voltage guard band, active droop mitigation etc.
  • Conduct end-to-end simulation studies including modeling of die/interposer/PKG/PCB/PMU, to meet stringent impedance and voltage droop spec.
  • Provide implementation guidelines and feedback to silicon, package, system design and other cross-functional teams.
  • Perform feasibility study for silicon floorplan, advanced droop mitigation schemes, voltage regulator modeling and tuning, system mockup design etc.
  • Perform model to hardware correlation on component and product/system level.

Qualifications

  • BS and 10 +years of relevant industry experience.
  • M.S and or Ph.D. with academic background in Power/Signal Integrity, Power Electronics or Analog Circuit Design.
  • Understanding of power supply architecture covering multi-stage voltage regulator technologies, PCB and package design trends and trade-offs, and chip supply design including low-power and high-power design methodologies.
  • Experience in PI/SI methodology development, PDN modeling from system to die, and lab correlation/validation.
  • Proficiency in Python coding, AI/ML assisted automation experience.
  • Experience in design and analysis of product power supply solution.
  • Deep understanding of Voltage Regulator design principles and electrical performance in the system environment.
  • Good knowledge in 3D/2D EM simulation tools, electromagnetic and transmission line theory.
  • Familiar with lab equipment including but not limited to VNA, real-time scope, spectrum analyzer.
  • Ability to work and communicate efficiently in a multi-functional teams.
