Proven experience verifying high-speed digital links through simulation and test, including pre- and post-layout SI/PI simulation (e.g., Keysight ADS, Ansys SIwave/HFSS, Cadence Sigrity, Siemens HyperLynx), IBIS/IBIS-AMI channel simulation, S-parameter extraction and analysis, and lab characterization using vector network analyzers (VNAs), TDR/TDT, high-bandwidth real-time and sampling oscilloscopes, BERTs, and eye diagram, jitter, and compliance measurements . Expertise in power integrity, including power distribution network (PDN) design to target impedance, decoupling strategy, DC IR drop and current density analysis, AC/frequency-domain PDN impedance analysis, plane resonance mitigation, and power delivery for high-current, low-voltage SoCs and FPGAs .
