Job summary

Samsung Semiconductor seeks an engineer to develop power and energy macromodels for die-to-die PHY and 2.5D interposer interconnect in C-HBM programs. Models are built from S-parameter interconnect data, calibrated against circuit references, and optimized for long workload traces to feed time-indexed power maps into trace-driven simulations.

The role requires strong Python, S-parameter familiarity, and CMOS power analysis, with onsite presence in San Jose, CA.

Qualifications

• Strong Python for numerical computing.
• Familiarity with S-parameters and frequency-domain analysis.
• Experience with SPICE-level circuit simulation.
• Understanding of dynamic switching power in CMOS drivers.

Responsibilities

• Develop energy and power macromodels from S-parameter models.
• Extract per-lane capacitance and relate to switching energy.
• Create circuit-level SPICE reference to calibrate models.
• Develop reduced-order model forms and compare accuracy.
• Design calibration stimuli and parameter extraction procedures.
• Ensure models run efficiently over wide buses and long traces.
• Analyze sensitivity to data patterns and operating points.
• Extend modeling approach to more interfaces and structures as needed.
• Deliver validated models and regression checks into the simulation pipeline.

Role Summary

We are seeking an engineer to develop power and energy macromodels for die-to-die (D2D) PHY and 2.5D interposer interconnect in C-HBM programs. The role builds these models from S-parameter models of the interconnect, calibrates them againstcircuit-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.

Reports to

SVP, R&D (Power & Thermal Lab)

What You’ll Do

• Develop 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 Bring

• Bachelors 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 Qualifications

• Exposure 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.
