Who is the trainer?

Andrei Vladimirescu is a key contributor to the SPICE program development at the University of California, Berkeley. His key achievements include the SPICE 2G6 release, on which leading commercial versions like HSPICE are based, a parallel SPICE called CLASSIE for Single-Instruction Multiple-Data (SIMD) architectures and the design of a SPICE HW accelerator. Andrei is the author of the leading text on circuit simulation, The SPICE Book, published by J. Wiley and Sons. In the EDA industry he managed several teams as R&D director for analog/mixed-signal tools at Daisy, Analog Design Tools, Valid and Cadence. He is currently a professor at UC Berkeley and Institut Superieur d?Electronique de Paris.
