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.
