BSCS, California Polytechnic State University, San Luis Obispo, 1984.  Concentration in hardware with 3 years of BSEE program.  Senior project:  designed, constructed, and delivered a microprocessor-controlled data acquisition system.

Experience:

Chapman Consulting, March 2006 - Present:

Consulting has financed my research and development on a tool to perform layout synthesis of standard cells and datapath elements. Three U.S. patents have been issued for this work and another is pending.

Custom software development for the Electronic Design Automation industry: neural networks; optical proximity correction; OASIS reader and writer; Verilog, VHDL, GDSII, LEF, DEF, Liberty, and SPICE parsers; IP design flow management; research work in transistor level layout synthesis.

Synplicity, Inc., October 2000 - May 2002, March 2003 - March 2006:

Worked on numerous Quality of Results (QoR) and infrastructure projects for Synplicity's ASIC logic and physical synthesis products including placement-aware timing optimizations; RTL-level timing-driven optimizations; gate-level timing optimizations; critical path analysis.

Chapman Consulting, October 1992 to October 2000; May 2002 to March 2003:

Custom software development for the Electronic Design Automation industry: Mask Tooling work including CMP pattern fill generation; automated circuit delay and power characterization using SPICE; research work in transistor level layout synthesis.

COMPASS Design Automation, July 1984 to June 1991:

Wrote a 2-D interconnect capacitance extractor; prototyped an interconnect resistance extractor; architected a rewrite of the DRC package, leading to a 15x speedup overall; developed a Mask Tooling automation package that became a corporate competitive advantage; co-developed an automated regression test suite manager.

Hired as Software Engineer I; promoted through the years to Staff Software Engineer.
