Full Job Description
What You'll Do

  • Develop and execute mixed-signal verification plans for high-current IVR designs.
  • Build and maintain analog behavioral models (Verilog-A / SystemVerilog real-number modeling) for power stages, integrated inductors, PDN, and analog blocks.
  • Perform analog-digital co-simulation using industry-standard tools (Cadence Xcelium + Spectre, Synopsys VCS + FineSim / CustomSim, or AMS Designer).
  • Verify digital control loops
  • Create testbenches for key performance metrics: transient response (load steps), loop stability, efficiency, ripple, over-current / over-voltage protection, and startup/shutdown sequences.
  • Run regressions across PVT corners, Monte-Carlo analysis, and corner-case scenarios.
  • Debug mixed-signal issues at both transistor-level and behavioral level.
  • Collaborate closely with analog designers, digital designers, and system engineers to close verification coverage.
  • Develop automated verification scripts and improve verification methodology for faster turnaround.
  • Support post-silicon validation by correlating simulation results with lab measurements.


What We're Looking For

  • 5+ years of hands-on experience in mixed-signal verification of power management ICs or analog/mixed-signal SoCs.
  • Strong proficiency in mixed-signal simulation flows:
  • Real Number Modeling (RNM) and Verilog-A behavioral modeling
  • Analog-digital co-simulation (AMS, VCS + Spectre, Xcelium)
  • Solid understanding of power converter topologies (buck, multi-phase, 3-level buck, switched-capacitor converters).
  • Good knowledge of digital control concepts for power converters (PID controllers, DPWM, digital feedback loops).
  • Experience with MATLAB/Simulink for system-level modeling and testbench reference generation.
  • Proficiency in SystemVerilog and UVM for digital/mixed-signal testbenches.
  • Familiarity with Cadence Virtuoso, Spectre, or Synopsys CustomSim for analog simulation.
  • Understanding of analog non-idealities (quantization effects, loop delay, sensor offsets, PDN resonances, inductor non-linearities).
  • BSEE / MSEE with 8+ years relevant experience.


Nice to Have

  • Experience verifying high-frequency IVRs, PoL regulators, or high-current power delivery systems.
  • Experience with SIMPLIS, PLECS, or Simulink for system-level power electronics validation.
  • Familiarity with digital PID controller verification and fixed-point arithmetic effects.
  • Exposure to advanced packaging and on-die inductor modeling.
  • Scripting skills in Python, Perl, or Tcl for automation.
