Objective: Senior Software Design Position

SummaryA highly productive, principal-level engineer with eighteen years of experience in the communications field looking to concentrate more fully on software design.

Expertise in the following technologies:• Embedded software development and scripting.• LAN and WAN communication and interconnect standards (10/100/1000Base-T, POS, ATM, T/E3, PCIe,

HyperTransport). • HDL design. Control and data path structures. Multiple clock domains. Resource sharing. Efficient use of

DSP blocks in FPGAs. DSP techniques in FPGA design.

Expertise with the following implementation tools:• C, C++, Python, Java, Javascript and Perl programming languages in both Windows and UNIX

environments.• Verilog and SystemVerilog. (Working knowledge of VHDL).• Altera, Xilinx, and Lattice tool flows and the Synplicity and ModelSim tools. • Mentor schematic capture and Cadence layout tools.• Lab equipment (SmartBits, Agilent and TEK oscilloscopes and logic analyzers, soldering station tools).

Accomplishment Highlights• Created a test script in Python to bring up a module and run a number of tests while recording the

results. This allowed the module to run through its functions in a thermal chamber for nine-corner testing. The script ran on cygwin, but had to launch a native Windows script to connect to some of the test equipment. It allowed the hardware under test to be connected to via telnet or a COM link and it output an Excel file with the results.

• Wrote diagnostic functions to test a quad 100Base-TX MAC/PHY and other parts of a router services card. These functions were written in C and used in a test suite for Quality Assurance and debugging.

• Wrote stand-alone applications that were included in the release of a foreign language teaching software under Microsoft Windows using the C++ MFC libraries. These applications allowed the user to practice using the foreign language in an interactive and entertaining way.

• Performed half of all design and coding of Game-Maker. Game-Maker was a WYSIWYG CAD product for creating tile-based arcade-style games for (486 era) PCs. It enabled users to create original games without any coding. Built using C and C++, Game-Maker incorporated features such as animation, music, sound effects, and full-screen scrolling. Set up and manned the company’s booth at the Consumer Electronics Show in Chicago.

• Designing an active web email client application using Meteor with a Mongo backend database on github. Coding is done in Javascript.

• Created a simple interactive Android game using Java under eclipse. • Specified, designed, wrote, compiled and tested control-path FPGAs using Verilog for several 40-

100Gbps optical modules using the Xilinx Spartan6 family. These FPGAs interface to the card's processor and ASICs and also contain control loops to keep the optics at their optimal operating points. One of these control loops comprised the injection of a dither tone onto a bias voltage through an off-chip DAC, retrieval of the output signal from an ADC, signal processing to extract the effect of the dither tone using DSP blocks, and then adjustment of the bias voltage according to the result. Implementing the optics control loops digitally in the FPGA saved valuable board space, allowing a size reduction of the module.

• Wrote HDL as part of a three person team for a 108,000-register FPGA with 7Mbits of memory, targeted to an Altera Stratix II 180 part. This design offloads up to two companion packet processors and enables generic classification, shaping, and replication of traffic at 10Gbps bi-directionally. My individual

accomplishments included interfacing to Altera’s SPI4.2 core, designing an interface to an external TCAM, and creating a weighted round robin algorithm to choose between multicast and unicast traffic. Created design constraints and performed the design compilation. Worked closely with the design verification team and the board design teams to smooth out issues with their tests. This design allows significant performance improvements over designs based on the packet processor alone.

• Implemented a multiple-channel modulator which allowed different modulation modes and symbol rates in an FPGA. Coded a module for BPSK, QPSK, 8PSK , and QAM encoding, one for an optimized root-raised cosine FIR filter, and glue logic to support between 1 and 48 channels at various bandwidths. Optimized the FIR filter design to take advantage of reuse among channels and zeros in the interpolated input stream.

• Architected and implemented a board design for an I/O base card for a LAN/WAN security router. Custom base card used either off-the-shelf PMC daughter cards for low-bandwidth IO or custom HyperTransport based cards for high-bandwidth I/O. Designed and coded an FPGA for data path processing and backplane interfacing with a custom SERDES protocol. Schematic design included a Broadcom communications processor for packet processing and control, PCI bridge to Fast Ethernet MACs for interfacing two redundant Switch/Services Cards, dual DDR DIMM interfaces, I²C peripherals, and HT and PCI interfaces for daughter cards. Also responsible for the FPGA implementation of the backplane protocol and system control.
