Embedded hardware engineer supporting existing and developing new products from design through production.

Designed Cyclone V based replacement CPU board for existing smart lighting product. Created u-boot driver for PCIe interface of Cyclone V (using linux driver as basis), debugged and enabled NVMe boot. Developed configuration and patch set and build script for generating QSPI flash image from u-boot-socfpga images.Supported existing production.Worked with external supplier to develop replacement power supplies. Walked hardware through various safety and regulation agency certifications.Supported customer service in the characterization of field failures and root causing failures of RMAed devices.Hacked linux and the FPGA design files until NVMe worked and was stable in linux.Developed u-boot drivers and hardware profile for embedded Cyclone V board.Developed new Light Engine hardware architecture utilizing Cyclone V and the Texas Instruments TPS92518HV dual channel LED controller.Created System Verilog bench to test all hardware features simultaneously by assigning tests a single or group of channels automatically. Simulation ran for 120 ms and tested a dozen features spread across more than a dozen output channels.Developed method to power small DC loads at the light fixture while being able to turn of the fixture load and communicate with the micro-controller based sensor pack.Developed a configuration for Ubuntu Server to act as a production master controller utilizing PXE boot for the cyclone V SOC based embedded systems.Developed Production flow scripts in python 3.7 or newer. Code reads CSV register descriptions and generates python object source code for reading and writing (to the bit level) of each control registers within the FPGA.Developed and supported a cloud based repository of production flow logs using rsync as the backup process and a method to push out production test updates. The new system would have been based on a VPN to simplify the transfer of data back and forth.

Managed the Hardware Engineering team for one year. Applied interpersonal skills toward the success of the hardware design team. Worked with mechanical and electrical design to create an engine with field replaceable power supplies. Worked with external vendor to create a specification for supplies and to validate design quality.Designed smart lighting systems hardware, including project management; architectural design; schematic design; RTL, FPGA, PCB, and analog design & debug; power supply specification, debug & test; production flow and analog calibration software design & debug.Worked with nearly everyone in hardware & software engineering, test, QA and even with marketing and sales to shape product design to suit as many requirements as possible.Worked with contract manufacturing to enable volume production and the testing and debugging of new hardware.Wrote many pages of documentation in various medias from Word to Web to Google Docs to help software, QA and production understand the hardware from the most abstract to detailed point of view.Projects:1. Managed project to create a Light Engine platform with removable power supplies.2. Designed inductor energy shunt to ensure PWM pulsing stays detectable at load. Fully simulated in Tina TI.3. Modified u-boot to support specific hardware configuration.4. Designed low cost PSOC-4 LED adapter, created in schematic and C.5. Modified linux open source smartctl to read age information from proprietary embedded storage device.6. Created / modified 3.4 linux kernel modules to interface to various custom hardware. Modules self instantiated and created /dev nodes automatically using mdev.7. Debugged and brought up new output converter board and C software to test and calibrate it.8. Designed power meter circuitry and C software to calibrate it.9. Designed Marvell 800 MHz ARM CPU board, including DDR layout with Hyperlynx.10. Designed FPGA in Verilog to control up to 64 channels of LED controllers.

Design Engineer working on CMOS Imagers, ASIC emulation in FPGAs, ASIC and algorithm validation, and image processing pipelines using Matlab.Performed design validation on RTL based hardware designs using shell scripts, NCVerilog, and Quickbench.Designed color pipeline modules to perform various features and functions of CMOS imagers including: Demosaic, defect correction, noise reduction, and aperture edge calculations.Tools:1. Xilinx ISE2. Synopsis synthesis and simulation3. Synplify Pro4. Matlab

Board level Hardware Engineer for VGA graphics accelerators. Designed the Diamond Viper V770 NVidia Graphics card. Derived multiple SKUs for the board. Project shipped millions of boards world wide.

Designed board level stand alone computers for use in coin operated video games. This included original design research, schematic design, FPGA design, board layout assistance, original bring up, debug, documentation, and support of firmware and software designers.Designed light gun to be accurate to within 4 pixels using a PLD.Worked with software and firmware engineers to bring up hardware.Designed the hardware found in Area 51 and Maximum Force which shipped 25K units world wide.

Designed high resolution monochrome computer video cards. Worked with PECL and ECL. Fell in love with video.
