“The Life of SPICE” by Dr. Laurence W. Nagel Omega Enterprises Consulting

Register here.


The integrated circuit industry thrives on constant change and new technology. It is curious, then, that the SPICE circuit simulation program, in one form or another, has been around the industry for almost fifty years. Engineers entering this business today weren’t even born when I released the first version of SPICE! In this talk, I will chart the journey of SPICE, starting as a teaching program at the University of California, Berkeley, and spreading into industry and launching a cottage industry of software houses writing and supporting “alphabet SPICE.” I also give credit to the early principals in this journey, and share some amusing experiences. No one can say for sure, but I will speculate on how this particular program has evolved and yet stayed pretty much the same. I can think of no other computer program that can make that claim.


Laurence W. Nagel is an independent consultant in the San Francisco Bay Area. He has worked in the integrated circuit industry for almost 50 years. While earning his BS, MS, and PhD degrees at the University of California, he developed the SPICE circuit simulation program which launched a cottage industry of SPICE simulation tools. Mr. Nagel then began a 20 year career at Bell Laboratories which included developing the ADVICE circuit simulation program; participating in the development of the Kull-Nagel bipolar model; designing analog circuits for submicron NMOS processes; working in the AT&T Intellectual Property Division on assertion of patents and negotiation of patent licenses; and serving as project manager in the development of the Celerity circuit simulation program. Mr. Nagel then joined Anadigics, Inc., where he managed simulation of RF integrated circuits; modeling and characterization of GaAs MESFET device processes; and importing silicon CMOS design tools and foundry support. In 1998, Mr. Nagel founded his own company, Omega Enterprises, to consult on analog circuit design, circuit simulation, semiconductor device modeling, and as an expert witness in patent litigation and trade secret misappropriation matters. In 2008, he returned to his native California where he now resides with his wife Jean in Kensington and operates his consulting company Omega Enterprises Consulting.
