 He then went to Berkeley in 1975 to work on SPICE (Simulation Program with Integrated Circuit Emphasis), a program initially developed by Larry Nagel and Donald Pederson to analyse and design complex electronic circuitry with speed and accuracy.It is claimed that nearly all electronic IC's have been designed using SPICE or a derivative since the 1980s.University of California, Berkeley awarded Newton a PhD in 1978 and unusually an Engineering Faculty position as well.
