Job Description

Mixed-Signal Design Engineer

TYLsemi

Role Description Architect, model, and implement digital PID / cascade control loops (voltage-mode, current-mode, or hybrid) for high-frequency multi-phase IVRs operating at 10–100 MHz. - Develop high-fidelity plant models in MATLAB / Simulink (averaged and switched models) using extracted parasitics from Ansys Q3D / SIwave (inductor matrices, PDN impedance, frequency-dependent losses). - Perform closed-loop stability analysis on switched power stages. - Translate validated MATLAB/Simulink controller models into production-quality RTL (Verilog / SystemVerilog) using HDL Coder or manual high-quality coding. - Design and implement supporting digital blocks: ADC interface, DPWM (digital PWM). - Collaborate closely with analog designers on loop compensation, sensor design, quantization effects, and delay budgeting. - Perform mixed-signal verification: co-simulation of RTL (VCS / Xcelium) with analog models (Spectre / APS) and behavioral models (Simulink / SIMPLIS / PLECS). - Analyze and optimize for area, power, timing, and metastability in the digital controller across PVT corners. - Support silicon bring-up, debug, and controller tuning on lab hardware. Qualifications - Strong mixed-signal background: Solid understanding of both analog power circuits (buck converters, 3-level buck, hybrid SC-inductor topologies) and digital control systems, digital filters etc. - Expert-level MATLAB / Simulink experience: Building averaged and switched power converter models, Control System Toolbox, Simscape Electrical, Frequency Response Estimation (FRE), PID tuning and discrete-time controller design. - Proven experience converting MATLAB/Simulink control algorithms into clean, synthesizable RTL (HDL Coder or hand-coded Verilog/SystemVerilog). - Deep knowledge of digital PID implementation challenges: quantization, sampling effects, computational delay, fixed-point arithmetic, and limit cycling. - Familiarity with high-frequency power converter control (10–100 MHz range) and digital PWM modulators (DPWM). - Experience with mixed-signal verification flows (analog-digital co-simulation). - Good understanding of analog effects impacting digital control: loop delay, sensor non-idealities, inductor non-linearities, PDN resonances. - Proficiency in digital design tools: Synopsys VCS, Verdi, Design Compiler, PrimeTime (or equivalent Cadence flow). - BSEE / MSEE or PhD with 8+ years of relevant experience in power management ICs or high-performance mixed-signal design. Requirements - Prior experience designing digital controllers for integrated voltage regulators (IVRs), point-of-load (PoL) converters, or high-current AI/HPC power delivery. - Knowledge of advanced topologies: 3-level buck, multi-level converters, hybrid switched-capacitor + inductive converters. - Experience with package-integrated magnetics, high-permeability materials, and PDN modeling (Ansys Q3D / SIwave). - Experience with formal verification or assertion-based mixed-signal verification.
