Technical member of R&D design group with responsibilities for test and design support of cable modem products.Embedded SW:Created many embedded software drivers for various lab projects. Most of these projects were coded up in some form of C programming language, also comfortable learning other languages as needed to quickly deliver results.Created embedded menu-driven program in bare-metal platform that could test thousands of registers, setup prototype network switch, and run a user-defined test suite. Created embedded Linux program that would allow custom remote terminal access to remote logic prototyping system.Created custom application within QtGUI platform to allow custom byte-swapping data transfers between PC and remote logic prototyping system. Verification:Created custom tests (C, Verilog) to cover corner-cases that would be included in regression simulation test suites. Provided debug (ie waveform analysis, rtl, firmware, sim code) and checked code fixes into revision control system (CVS, RCS).HW Design:Created system level test-bus architecture for module-level debug visibility in ASIC/FPGA.Responsible for fast-clock subsystem blocks, required occasional IP integration of updated STxP70 processors & DMA modules. Provided on-going maintenance for many modules, such as adding new features or resolving timing issues by leveraging vendor provided tools.

(acquisition of Scientific-Atlanta, Inc. in 2006)My role was to create custom SW/HW test solutions in an effort to validate & improve the quality of our digital ASIC designs. This position was very unstructured and required intense time management skills to complete a wide range of tasks.Validation/Debug• Developed exhaustive characterization studies on set-tops containing corner-process ASICs.• Developed low power studies to isolate ASIC energy consumption in a system.• Performed failure analysis on field returned set-top boxes with lab experimentation and programming.• Extensive bench testing and experimentation using logic analyzers, oscilloscopes, and protocol analyzers (USB/PCIe/wireshark).• Extensive PCB rework as needed for lab studies and experiments.Embedded SW• Developed extensive embedded software applications in C (Cygwin) to characterize and debug ASIC behavior in a system environment of a cable set-top box hosted by MIPS/SPARC processors.• Created custom embedded USB2.0 driver code based on EHCI specification to allow video playback and unique FAT32 implementation on engineering set-top box.• Developed PIC microcontroller code for LCD display and keypad control on complex FPGA platform.• Created several SPI to TCP/IP debuggers based on 8051 MCU.• Developed firmware that would allow a set-top to become a JTAG boundary scan tester.PCB design• Designed prototype PCB test-boards to support each new ASIC release, typically mated with a production set-top box allowing special instrumentation needed for engineering development.• Designed complex stand-alone prototype platforms around home gateway ASIC that were used for customer demonstrations and home trials. Design elements supported: I2C, SPI, SATA, PCIe, RS-232, DOCSIS, MoCA, Ethernet, DDR2, FLASH, USB, and JTAG.RTL design• RTL integration and verification of USB2.0 IP into home gateway ASIC.• Developed behavioral simulation tests in Verilog and SystemC for ASIC/FPGA.

Member of ASIC design group responsible for providing validation and prototype solutions for new designs in engineering development. This position required a lot of creativity and initiative to verify how a prototype ASIC design would operate in the system environment of a digital cable set-top box. Some activities included:• Developed embedded C code to test and characterize ASIC behavior. • Designed prototype engineering boards to instrument and provide socket for ASIC.• Debugged complex engineering problems common to ASIC & system development.• Designed and executed "proof of concept" lab experiments as needed.• Extensive benchtop testing using circuit modifications, power supplies, meters, and oscilloscopes.• Extensive stb PCB rework as needed such as power supply hacks to run voltages up/down, inserting custom circuitry, cutting traces, signal integrity improvement, component replacement down to 0201...essentially did any kind of rework short of BGA swapping.• Created corner-process studies to validate design and to determine maximum microprocessor and DDR clock frequencies to be used in production firmware.
