I am a self-driven veteran of the ASIC/FPGA AND IC design in the tech industry, with over 20 years of experience across all technical disciplines of semiconductors chip/ASIC or IC design as well as FPGA design, extensive hands-on experience as well as managing cross-functional international teams through all aspects of the chip design through production. I have a proven track record of successful, time-crunched seemingly "impossible" tape-outs of flagship products. When I’m not doing chips, I hack computer vision and deep learning to fit on platforms such as Raspberry-Pi.
I am also an Expert Witness for patent infringement and liability cases that involve Semiconductors, FPGAs, Hardware, Software, Embedded Firmware, and EDA/CAD tools and the owner of GR Tech - an expert witness firm that covers various areas such as networking, wireless communications, cellular communications, software, firmware, hardware, ASIC, FPGA, semiconductors, radar signal processing, computer vision and image processing, signal processing, algorithms, optics and optical systems, RF and antenna design and sensors, for post and pre-litigation.
Owner of an Expert Witness firm that is giving expert witness services in patent infringement and liability cases, that involve semiconductors, mobile devices, hardware, software, firmware, optics, RF and Antenna, consumer electronics, networking, wireless and cellular communications, radar signal processing, computer vision and image processing, algorithms and more.
We also do a lot of reverse engineering of hardware and software for pre-litigation and hardware and software reviews for ongoing litigations.
Extensive IP (Intellectual Property) experience
patent development, analysis, licensing, and strategic positioning. Holds 6 patents.
Architecture and RTL Design and verification
hands-on experience with architectures of many SoCs and complex blocks as well as RTL writing and functional verification for both ASIC and FPGA. Extreme knowledge in design for PPA, i.e. architecting an SoC to meet timing, power and area budgets from the get-go, making the rest of the flow almost a push button.
From whitepapers to publications, I am consistently writing and teaching my craft to others
Extensive hands-on experience with the following tools
SoC architecture design Verilog and RTL design, Functional Verification, physical synthesis, timing closure, place and route, DFT, extraction, clock tree synthesis, Perl scripting, Python, Git/CVS/Mercurial, Tcl, Timing constraints design, Running computer vision in real time on platforms like Raspberry Pi
Over 20 years of experience
in developing a range of product areas: networking, wireless/cellular communications, Switch ASICs CPUs, DSPs, FPGAs, software, firmware, system, IPs, CAD/SW tools.
Over 12 years of experience
in senior management of design and production of integrated circuits, FPGAs, SW, and CAD tools, from conception to mass-production.
Many successful unique complex, SoCs
brought from concept to volume production in multiple companies. Many more tape-outs, shrinks, and product derivatives were brought to production. Covering 65nm down to 10nm processes
EDA tools and IP
Responsible for all IP and EDA tools. Negotiated agreements for the purchase of EDA/CAD tools silicon, IP, other vendors, and known foundries for over $20M
