ORG Purdue University - Main Campus Title BIO Michael McLennan received a Ph.D. in 1990 from Purdue University for his dissertation on dissipative quantum mechanical electron transport in semiconductor heterostructure devices. He is co-inventor on a patent for a novel DRAM bit-line clamping circuit developed at IBM. He joined Bell Labs in 1992 to work on tools for semiconductor device and process simulation, and he became an enthusiast of a scripting language called Tcl. He is co-author of "Effective Tcl/Tk Programming" (published by Addison-Wesley) and "Tcl/Tk Tools" (published by O'Reilly and Associates). He also developed [incr Tcl], an object-oriented extension of Tcl, which is now used by thousands of developers worldwide on projects ranging from the TiVo digital video recorder to the Mars Pathfinder. Along the way, he used Tcl to develop CAD tools at various levels in the semiconductor design and manufacturing chain, including device/process simulation, circuit simulation, and HDL design flow. Dr. McLennan is the Software Architect for the CCD project. Having more than 12 years of professional experience at semiconductor companies, including Bell Labs and Cadence Design Systems, he has a strong background in Computer-Aided Design (CAD) tools and software development practices. He coordinates the development efforts for CCD, making sure that the various parts-the job sequencer, the e-Lab Notebook Server, and the visualization environment-all work together in a coherent system. He also guides the user interface design, acting as a liaison between scientists and software developers.
