Research Interests

Custom Analog Circuit CAD

A majority of the new application-specific integrated circuits (ICs) designed today require a core of custom analog circuitry for data acquisition, interfacing with the outside world, wireless cellular links, signal processing, and speech or vision front-end processing. The continuing lack of automatic circuit synthesis and layout tools for these applications remains a huge bottleneck. This research involves work on numerical algorithms to translate specifications into circuits, on optimization algorithms to improve the performance and manufacturability of these circuits, and on combinatorial algorithms to translate these circuits into final integrated circuit mask geometry.

High-Performance Digital ICs and CAD

This work focuses on high-performance digital ICs, where it is necessary to handle both large problems and subtle electrical interactions. Projects include digital clock-tree routing and sizing for high-speed designs; timing-driven layout tools for field-programmable gate arrays (FPGAs), wherein both the logic and the pattern of wiring connections are programmable by the user; and leaf-cell synthesis for random logic in custom designs, such as microprocessors. Work here involves a mix of combinatorial algorithms and electrical circuit verification algorithms.
