The role builds these models from S-parameter models of the interconnect, calibrates them against circuit-level references, and makes them fast enough to run over long workload traces. The resulting models feed time-indexed power maps into the trace-driven power and thermal simulation flow.Location: Daily onsite presence at our San Jose, CA in alignment with our Flexible Work policyReports to: SVP, R&D (Power & Thermal Lab)What You’ll DoDevelop energy and power macromodels of interposer interconnect and PHY transmit front-ends from S-parameter models of the channel.Extract per-lane self-capacitance and inter-lane mutual capacitance from the network parameters, and relate them to switching energy.Build a circuit-level reference in SPICE and use it to calibrate the macromodels and bound their error.Develop and compare reduced-order model forms, and select among them by measured accuracy.Design calibration stimuli and parameter-extraction procedures.Ensure models evaluate efficiently over wide buses and long workload traces.Analyze sensitivity to data pattern, bus encoding, activity factor, and operating point.Extend the modeling approach to additional interfaces and interconnect structures as the program scope grows.Deliver validated models and regression checks into the trace-driven simulation pipeline, and collaborate with software engineers on model interfaces.What You BringBachelors degree with 5+ years of experience or Masters degree with 3+ years of experience preferred or PhD Degree with 0 years of experience.Strong Python for numerical and scientific computing. Proven self-discipline and professional maturity to execute independent research and meet rigorous milestones with a strong sense of accountability for both personal and collective goals in a fast-paced, on-site environment.Familiarity with S-parameters and frequency-domain network analysis.Experience with SPICE-level circuit simulation.Understanding of dynamic switching power in CMOS drivers and interconnect, including coupling capacitance.Ability to abstract circuit behavior into compact analytical or table-based models.Familiarity with RTL/SystemC simulation flows and how power models are used in them.Deep knowledge and experience in Thermal Engineering.Expertise in FloTHERM and familiarity with other CFD tools.Excellent technical writing and verbal communication skills for collaboration, documentation, and presentations. Preferred QualificationsExposure to UCIe or other die-to-die interfaces, high-speed I/O, or 2.5D packaging.Hands-on experience with power analysis tools such as PrimeTime PX, StarRC, or Verdi.Experience running large parameter sweeps or parallelized analysis.Prior experience in power or thermal modeling.What We OfferThe pay range below is for all roles at this level across all US locations and functions.
