Role Overview

The role involves end-to-end mixed-signal verification of high-current IVR designs, including developing behavioral models, performing analog-digital co-simulation, and verifying digital control loops and key power-performance metrics. The candidate will be responsible for creating testbenches, running PVT and Monte Carlo regressions, debugging transistor- and behavioral-level issues, and developing automation to improve verification efficiency. The role also requires close collaboration with analog, digital, and system teams and support for post-silicon validation.

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

- 8 to 15 years of hands-on experience in mixed-signal verification of power management ICs OR analog/mixed-signal SoCs.

- Robust 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.
