SerDes System Modeling and Simulation
February 2010 – Present

Focus on modeling high speed digital (HSD) integrated circuits (ICs) based on the industry Input/Output Buffer Information Specification (IBIS) Algorithmic Model Interface (AMI) standard. Created a 2 day AMI Training class for Keysight Technologies for their AMI modeling flow based on their SystemVue and Advanced Design System (ADS) tools. Conducted AMI Training at over 30 high speed digital IC semiconductor companies. Created custom transmit (TX) and receive (RX) AMI models for many customers including adaptive continuous time linear equalizer (CTLE) designs, clock and data recovery (CDR) designs, and more.

Electronic System Level (ESL) Design Manager at Keysight Technologies (retired)

Note: Keysight Technologies was spun off from Agilent Technologies, which was spun off from Hewlett Packard, which bought EEsof Inc.

February 1987 – October 2009

  • Manager for the SystemVue ESL software product including data flow simulation technology development with initial product launch in 2009 as the Electronic Design Automation (EDA) product which provides superior Digital Signal Processing (DSP) and Radio Frequency (RF) system level codesign.
  • Managed the Advanced Design System (ADS) software product growth in wireless and communications (comms) system applications providing superior RF circuit verification (1998 through 2009).
  • Managed the ADS DSP implementation path including cosimulation with digital Hardware Description Languages (HDLs) in 1999.
  • Managed the comms system cosimulation with Circuit Envelope simulation technology in 1998 which provides superior system level circuit verification flow.
  • Initiated in 1997, with continued success through to-date, the Agilent EEsof comms modeling focused China design center in Beijing.
  • Managed the adoption and development of the University of California (UC) Berkeley’s Ptolemy (data flow simulation software) into the Advanced Design System (ADS) simulation software product in 1997 as the first EDA commercial use of Ptolemy.
  • Managed the development of instrument links for RF/comms systems analysis within the system simulation software.
  • Initiated and led the development of DSP with RF system design as EDA’s first system simulation tool combining RF and DSP in 1994.
  • Initiated and led the development of RF/comms system design with EDA’s first RF envelope time domain system simulator in 1992.
  • Initiated and led the development of RF circuit cosimulation with RF system simulation software in 1990.
  • Initiated and led the development of RF system level Budget analysis with inclusion of full linear and nonlinear scattering (S) parameters and noise parameters in 1989.
  • Initiated and led the development of OmniSys, the first EDA frequency domain based Radio Frequency (RF) system design and simulation tool, with initial release in 1988.
