AMS Modeling Engineer

We are seeking an Analog IP Modeling Engineer specializing in SystemVerilog Real Number Modeling (RNM). In this role, you will bridge the gap between analog design and digital verification by creating high-speed, accurate behavioral models (wreal/EE_pkg) for complex analog IPs.

Your work will enable full-chip SoC verification by replacing slow SPICE simulations with high-performance event-driven models.

Key Responsibilities:

• Model Development: Develop, verify, and maintain SystemVerilog RNM models for analog IPs (e.g., PLLs, ADCs, DACs, SerDes, PMIC, and LDOs).
• Model Architecture: Define modeling strategies using SystemVerilog-AMS, wreal, or User Defined Nettypes (UDN) to balance simulation speed and physical accuracy.
• Verification & Calibration: Perform model-to-schematic equivalence checking to ensure the behavioral model matches the golden SPICE/Spectre circuit simulations.
• Integration: Support SoC integration teams by providing models compatible with UVM environments and mixed-signal simulation tools (e.g., Cadence Xcelium/Virtuoso, Siemens Questa ADMS).
• Automation: Develop scripts (Python/Perl/Tcl) to automate model generation and verification flows.

Required Skills & Qualifications:

• SystemVerilog Proficiency: Expert knowledge of SystemVerilog, specifically Real Number Modeling (RNM) and the EE_pkg (IEEE or later).
• Analog Knowledge: Strong understanding of analog circuits, including feedback loops, frequency domain analysis, and noise modeling.
• EDA Tools: Hands-on experience with mixed-signal simulators such as Cadence Virtuoso/Xcelium (AMS Designer) or Synopsys VCS/CustomSim
• Languages: Proficiency in C/C++, Python, or Verilog-A for auxiliary modeling and automation.
• Methodology: Familiarity with UVM (Universal Verification Methodology) as applied to mixed-signal environments.

Preferred Qualifications:

• Experience with Event-Driven Analog (EDA) modeling techniques.
• Knowledge of signal integrity concepts and high-speed link modeling (e.g., IBIS-AMI).
• Degree in Electrical Engineering or a related field with 3+ years of industry experience.
