Prof. Donald O. Pederson (September 30, 1925 - December 25, 2004) of UC Berkeley was a
pioneering visionary in solid-state circuit design. He was the originator and, with his students,
was the driving force behind the SPICE circuit simulation program, which has become the
ubiquitous simulation program for detailed digital, memory, and analog circuit design at the
transistor level throughout the industry, a position it has continued to maintain for over two
decades to the present time. SPICE was released into the public domain, and quite literally
spawned the EDA industry. His impact on the electronics industry was recognized most notably
by the IEEE in 1998, when he was named the recipient of the IEEE Medal of Honor. He became
a member of the National Academy of Engineering in 1974 and the National Academy of
Sciences in 1982, as well as receiving many other awards.

SPICE HISTORY
• First Released in 1971 and announced in
1973 at the Sixteenth Midwest Symposium
on Circuit Theory
– Rapidly adopted by universities and industry
in the early 1970’s
• SPICE 2G6 became the de facto industry
standard in the late 1970’s
– Why did this happen?
Sld 3 • Chabot College Engineering • Bruce Mayer, PE • BMayer@ChabotCollege.edu PSPICE_Install-n-DC.pptx
Origins of SPICE
• SPICE began as an innovative class project
under the direction of Ron Rohrer in the
academic year 1969-1970
• The class topic was circuit synthesis but
became a class on circuit simulation
– Students learned by doing --- They wrote a
simulator!
• The final judge of success was Don Pederson
– Larry Nagel was Liaison to Prof. Pederson
Sld 4 • Chabot College Engineering • Bruce Mayer, PE • BMayer@ChabotCollege.edu PSPICE_Install-n-DC.pptx
Why SPICE Was Successful
• FREE and in the Public Domain
• DC, AC, Transient, Noise, and
SensitivityAnalyses in the same program
• Built-in models for diodes, bipolar transistors,
MOSFETs, and JFETs
• Heavy use of SPICE by students led to many
improvements in robustness
– At the time, could handle fairly large circuits
• Written in fairly portable FORTRAN
Sld 5 • Chabot College Engineering • Bruce Mayer, PE • BMayer@ChabotCollege.edu PSPICE_Install-n-DC.pptx
SPICE2
• First released into the public domain in1975
• Contained all features of SPICE
• Data structures totally revamped to
incorporate dynamic memory allocation
• Thorough upgrade of DC convergence and
transient numerical integration algorithms
• About 8,000 lines of FORTRAN
• SPICE2 was used as a platform for research
that spawned hundreds of research projects
Sld 6 • Chabot College Engineering • Bruce Mayer, PE • BMayer@ChabotCollege.edu PSPICE_Install-n-DC.pptx
Industrial Use of SPICE2
• Many industrial research centers adopted
SPICE2 and developed proprietary versions
of the program, including
– Bell Labs (ADVICE), Texas Instruments
(TISPICE), Motorola (MCSPICE)
• Shawn and Kim Hailey formed Meta Software
(Campbell, CA) and modified a copy of
SPICE 2E into the most successful
version of a commercial
SPICE known as HSPICE
Sld 7 • Chabot College Engineering • Bruce Mayer, PE • BMayer@ChabotCollege.edu PSPICE_Install-n-DC.pptx
SPICE3
• In 1989, SPICE3 was released into the
public Domain
• This later version of SPICE3 was coded in
the C language and utilized the more
sophisticated data structures of C
• SPICE3 contains about 135,000 lines of
C code
• The latest version, 3F5, was released in 1993
Sld 8 • Chabot College Engineering • Bruce Mayer, PE • BMayer@ChabotCollege.edu PSPICE_Install-n-DC.pptx
Commercial Use of SPICE3
• The Company MicroSim adapted a version
of SPICE3 for the most popular of all SPICE
programs  PSPICE
• Many other companies utilized SPICE3 as a
platform for additional “alphabet SPICE”
programs; e.g. LTspice
