• 200 - 300 Employee

• Principal FPGA Engineer

  • Nov 2012 - Present

  Working on transformative medical imaging technology with a world class cross disciplinary team. Early employee whose design decisions are integral to the Butterfly iQ, the world's first whole-body FDA approved ultrasound probe that plugs into a smartphone and costs less than $2000. - Lead engineer for the company's FPGA designs. Responsible for distilling system requirements into an architecture that can be realized in hardware. This may include FPGA part selection, internal and external hardware architecture design, and hardware/software interface design. - Coding in SystemVerilog and verification with Mentor Graphics QuestaSim. Extensive experience with Intel/Altera Quartus II and Microchip/Microsemi Libero SoC. - Embedded software experience with NIOS II, RISC-V, and C. - Highlights of designed modules include DSP blocks, external I/O interfaces, system control, and debug interfaces. - Extensive system integration, test, and debug work.

Motorola Solutions

• Software Development
• 400 - 500 Employee

• Senior Staff Hardware Engineer

  • May 2000 - Oct 2012

  - Architected and led a team of 4 in the design of a complex hardware abstraction layer in an FPGA. Design will be used in Motorola Solutions' flagship base radio product. Design includes 7 soft core processors, custom hardware interface logic, innovative debug interfaces, and more. Hierarchical design built on Altera Qsys SoC environment. Created integrated HDL/embedded software build environment. Pioneered version control and best practices for multiple parallel FPGA designers within the department. - Architected, designed, and implemented an FPGA design incorporating multiple DSP audio processing functions including IIR filters, equalizer, >150 Goertzel tone detectors, tone generators, and more. Included soft core processor for control plane functionality. Wrote embedded software. Altera DSP Builder design. - Architected and Implemented an FPGA based parallel data switch that allows 4 cryptography engines and 2 quad-core DSPs to exchange data via independent parallel busses while still acting as bus masters. - Architected, designed, and drove to fruition an automated test fixture capable of simultaneously testing up to 8 MCC 7500 radio dispatch products each in 5-8 minutes versus 90 minutes required for manual testing. The fixture was used for design validation testing, factory test, and analysis of customer returns. It includes an FPGA based test board with over 100 relays for signal routing. Wrote the embedded software that runs on the FPGA soft-core processor as well as the higher level LabView application that controls the units under test, the (routing) test board, and the other test equipment. - Experienced with all aspects of digital hardware design: requirements generation, architecture, circuit design, component selection, schematic entry, layout oversight, timing analysis, capacitive loading analysis, prototype testing, interface/standards testing, acoustics testing, and regulatory testing.
