Austin, Texas & Irvine, Ca

R&D in analog/mixed signal simulation.

Costa Mesa, Ca

Worked on IBM's PowerSPICE circuit simulator for noise, power, static timing analysis (STA) and library characterization. Critical contributions include:* Acted as liaison between simulation and timing teams to ensure timely response to customer requests and issues.* Pre-simulation circuit partitioning where large channel connected component (CCC) memory array circuits get “pruned” at the API level prior to entering the simulator, providing huge savings in memory and cpu time. * Methodology for optimized and accurate MOSFET pin capacitance calculation for STA. * Methodology for SOI body charge initialization. This enabled more efficient method of body charge initialization (as opposed to body voltage initialization) in BSIM SOI devices in PowerSPICE to account for the history effect.* Pruning of large CCCs based on MOSFETs known to remain OFF during STA simulations. * Performance tuning; improving memory footprint and runtime through profiling and algorithmic enhancements.

East Fishkill, Ny - Costa Mesa, Ca

Led a cross EDA/Research team to transform an IBM Research SPICE-like circuit simulator engine to a production-quality API-driven simulator capable of handling SPICE and ASTAP languages and BSIM device models. Critical contributions included:* Interface to a simulator front-end module for netlist parsing and evaluation services* Interface to the IBM-standard simulator/device interface for BSIM device evaluation* On-demand, table lookup based device models for improved simulation performance. Acted as one of the key contributors during the development and qualification phases of an explicit event-driven simulator in IBM EDA. Main contributions included improvements to its core engine, linear solver and partitioning algorithm for efficient simulation and fundamental changes to its backward Euler algorithm to improve simulation robustness for extracted netlists.

Paterson, Nj

* Extended Compact Software's full-wave 2.5-D electromagnetic simulation tool, Microwave Explorer, used for packaged MMIC applications (microstrip and stripline circuits) to an open-environment simulator capable of handling planar (patch) antennas. * Developed a simulation tool for a quasi-static amplifier design project under SBIR using Microwave Explorer framework.
