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.

N********ice 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.
