Birthplace of the SPICE Circuit Simulation Program, 1971

Plaque citation summarizing the achievement and its significance:


200-250 word abstract describing the significance of the technical achievement being proposed, the person(s) involved, historical context, humanitarian and social impact, as well as any possible controversies the advocate might need to review.


IEEE technical societies and technical councils within whose fields of interest the Milestone proposal resides.


In what IEEE section(s) does it reside?

Oakland-East Bay Section

IEEE Organizational Unit(s) which have agreed to sponsor the Milestone:

IEEE Organizational Unit(s) paying for milestone plaque(s):


IEEE Organizational Unit(s) arranging the dedication ceremony:


IEEE section(s) monitoring the plaque(s):


Milestone proposer(s):


Please note: your email address and contact information will be masked on the website for privacy reasons. Only IEEE History Center Staff will be able to view the email address.

Street address(es) and GPS coordinates in decimal form of the intended milestone plaque site(s):

Cory Hall, University of California, Berkeley CA 94720

Describe briefly the intended site(s) of the milestone plaque(s). The intended site(s) must have a direct connection with the achievement (e.g. where developed, invented, tested, demonstrated, installed, or operated, etc.). A museum where a device or example of the technology is displayed, or the university where the inventor studied, are not, in themselves, sufficient connection for a milestone plaque.

Please give the address(es) of the plaque site(s) (GPS coordinates if you have them). Also please give the details of the mounting, i.e. on the outside of the building, in the ground floor entrance hall, on a plinth on the grounds, etc. If visitors to the plaque site will need to go through security, or make an appointment, please give the contact information visitors will need. The plaque will be affixed to a permanent wall just inside the main entrance to Cory Hall at the University of California, Berkeley, CA 94720 USA. Cory Hall is the Electrical Engineering building at UC Berkeley and is the building where all three versions of SPICE were developed.

Are the original buildings extant?

Yes

Details of the plaque mounting:


How is the site protected/secured, and in what ways is it accessible to the public?

The site is protected by University of California staff and security. This is a public area, well lit, accessible to the public without restriction Monday to Friday from 7AM to 6:30 PM local time. No appointment requirements nor security barriers limit access at those times. There are often events, open houses, and parties organized nearby, and there is a lot of visitor and student traffic there.

Who is the present owner of the site(s)?

Regents of the University of California

What is the historical significance of the work (its technological, scientific, or social importance)? If personal names are included in citation, include justification here. (see section 6 of Milestone Guidelines)

For the past forty years, SPICE (an acronym for Simulation Program with Integrated Circuit Emphasis) has been an essential computer-aided design (CAD) tool for the design of integrated electronic circuits. It also has been an essential tool for teaching electronic circuits to undergraduate engineering students. Within a few years after the original development, SPICE had achieved acceptance at almost all electrical engineering schools and had started a cottage industry to supply SPICE derivatives to the rapidly expanding integrated circuit industry. To this day, SPICE and its commercial derivatives are widely used in industry and academia for the design of integrated circuits.

What obstacles (technical, political, geographic) needed to be overcome?

SPICE began as a class project of a series of courses taught by Professor Ronald A. Rohrer. The course was about circuit simulation, and Ron, always an innovative teacher, figured the class would learn more by doing than by listening to him lecture. The rule was that Don Pederson had to approve of the program for the class students to receive a passing grade. Ron Rohrer's class project idea was a smashing success. In one year, the class developed a simulation program that combined a sparse matrix solver, implicit integration algorithms, and adjoint solution methods into one program that would evolve into the industry-standard circuit simulation programs.

What features set this work apart from similar achievements?

SPICE was the latest of circuit simulation programs to be developed at UC Berkeley under the supervision of the late Professor Donald O. Pederson. In common with the previous programs, SPICE was intended for instructional use and had a straightforward input syntax that included built-in models for semiconductor devices. SPICE was the first program to combine the circuit analysis capabilities of DC analysis, AC analysis, and transient analysis. It was the first simulation program to utilize sparse matrix techniques to allow simulation of circuit sizes orders of magnitude larger than previously possible. It also utilized the relatively new concept of the adjoint network to provide efficient sensitivity analysis and noise analysis. In common with previous programs developed under Professor Pederson, SPICE was released into the public domain, an early example of what is now known as open source software.

Professor Pederson was the 1998 recipient of the IEEE Medal of Honor, with the citation: "For creation of the SPICE Program, universally used for the computer aided design of circuits."

Supporting texts and citations to establish the dates, location, and importance of the achievement: Minimum of five (5), but as many as needed to support the milestone, such as patents, contemporary newspaper articles, journal articles, or chapters in scholarly books. 'Scholarly' is defined as peer-reviewed, with references, and published. You must supply the texts or excerpts themselves, not just the references. At least one of the references must be from a scholarly book or journal article. All supporting materials must be in English, or accompanied by an English translation.


Supporting materials (supported formats: GIF, JPEG, PNG, PDF, DOC): All supporting materials must be in English, or if not in English, accompanied by an English translation. You must supply the texts or excerpts themselves, not just the references. For documents that are copyright-encumbered, or which you do not have rights to post, email the documents themselves to ieee-history@ieee.org. Please see the Milestone Program Guidelines for more information.


Please email a jpeg or PDF a letter in English, or with English translation, from the site owner(s) giving permission to place IEEE milestone plaque on the property, and a letter (or forwarded email) from the appropriate Section Chair supporting the Milestone application to ieee-history@ieee.org with the subject line "Attention: Milestone Administrator." Note that there are multiple texts of the letter depending on whether an IEEE organizational unit other than the section will be paying for the plaque(s).

Please recommend reviewers by emailing their names and email addresses to ieee-history@ieee.org. Please include the docket number and brief title of your proposal in the subject line of all emails.
