What You'll Learn
SPICE is an interpreted language
SPICE (Simulation Program with Integrated Circuit Emphasis) is a general-purpose, open-source analog electronic circuit simulator. It is a program used in integrated circuit and board-level design to check the integrity of circuit designs and predict circuit behaviour. SPICE is an interpreted language, meaning that in order for a computer to understand the SPICE instructions, the device must have the SPICE program (interpreter) installed. SPICE source files are commonly referred to as "netlists", with each line in the file being called a "card". Netlists are created by typing instructions line-by-line using a word processor or text editor. Text editors are preferred over word processors for any type of computer programming as they produce pure ASCII text with no special embedded codes for text highlighting, which are uninterpretable by interpreter and compiler software.
SPICE was developed at the Electronics Research Laboratory of the University of California, Berkeley, by Laurence Nagel, with direction from his research advisor, Prof. Donald Pederson. SPICE1 is largely a derivative of the CANCER program, which Nagel had worked on under Prof. Ronald Rohrer. CANCER stands for "Computer Analysis of Nonlinear Circuits, Excluding Radiation". At the time, many circuit simulators were developed under contracts with the United States Department of Defense to evaluate the radiation hardness of a circuit.
SPICE is the industry-standard way to verify circuit operation at the transistor level before committing to manufacturing an integrated circuit. The SPICE simulators help predict the behaviour of the IC under different operating conditions, such as different voltage and current levels, temperature variations, and noise. SPICE can also be applied beyond the electrical realm, such as in thermal simulations, as thermal systems may be described by lumped circuit elements mapping onto the electronic SPICE elements.
SPICE has been applied in various fields, including operations research to evaluate perturbed supply chains, and in modelling loudspeakers, earphones, and headphones. SPICE has also been used to model the interface between biological and electronic systems, such as in synthetic biology and the virtual prototyping of biosensors and lab-on-chip.

SPICE is open-source software
SPICE (Simulation Program with Integrated Circuit Emphasis) is a general-purpose, open-source analog electronic circuit simulator. It is a powerful program used in integrated circuit and board-level design to check the integrity of circuit designs and predict circuit behaviour. SPICE was developed at the Electronics Research Laboratory of the University of California, Berkeley, by Laurence Nagel, with direction from his research advisor, Prof. Donald Pederson.
SPICE is widely used in the industry as it allows designers to verify circuit operation at the transistor level before committing to manufacturing an integrated circuit. This is essential as the high costs of photolithographic masks and other manufacturing prerequisites make it imperative to design the circuit to be as close to perfect as possible before the integrated circuit is first built. SPICE helps predict the behaviour of the circuit under different operating conditions, such as different voltage and current levels, temperature variations, and noise.
SPICE source code was initially distributed by UC Berkeley for a nominal charge to cover the cost of magnetic tape. The license originally included distribution restrictions for countries not considered friendly to the US, but the source code is currently covered by the BSD license. SPICE has inspired and served as the basis for many other circuit simulation programs in academia, industry, and commercial products.
SPICE has several free and open-source implementations available, such as SIMetrix Spice, which offers a free demo version suitable for small circuits. ngspice is another open-source Spice circuit simulator that is compatible with PSPICE and LTSPICE device model parameters and netlists for simulating discrete circuits. It offers a wealth of device models for active, passive, analog, and digital elements, and the source code is available for download.
SPICE is an interpreted language, and its input and output formats are plain text, making it universal and easy to edit. SPICE instructions can be typed into a text editor or word processor, and the output can be modified to suit specific formatting needs.

SPICE simulates analog circuits
SPICE (Simulation Program with Integrated Circuit Emphasis) is a general-purpose, open-source analog electronic circuit simulator. It is a program used in integrated circuit and board-level design to check the integrity of circuit designs and predict circuit behaviour. SPICE is considered the industry-standard way to verify circuit operation at the transistor level before committing to manufacturing an integrated circuit.
SPICE was developed at the Electronics Research Laboratory of the University of California, Berkeley, by Laurence Nagel, under the direction of his research advisor, Prof. Donald Pederson. SPICE1, first presented at a conference in 1973, is largely a derivative of the CANCER program (Computer Analysis of Nonlinear Circuits, Excluding Radiation), which Nagel had worked on under Prof. Ronald Rohrer.
SPICE source files are commonly referred to as "netlists", with each line in the file called a "card". Netlists are created by typing instructions line-by-line using a word processor or text editor. SPICE only understands netlists, and each line of the source file represents a different component of the circuit diagram. For example, "v1 represents the battery (voltage source 1), positive terminal numbered 1, negative terminal numbered 0, with a DC voltage output of 15 volts". SPICE simulators can predict the behaviour of the IC under different operating conditions, such as different voltage and current levels, temperature variations, and noise.
SPICE has been applied to a wide range of simulations, including modelling the interface between biological and electronic systems, operations research to evaluate supply chains, and modelling loudspeakers, earphones, and headphones. SPICE has also been used to simulate analog circuits, with LTspice® being a popular SPICE simulator software that includes enhancements and models for improving the simulation of analog circuits.

SPICE's plain-text input and output
SPICE (Simulation Program with Integrated Circuit Emphasis) is a general-purpose, open-source analog electronic circuit simulator. It is a program used in integrated circuit and board-level design to check the integrity of circuit designs and predict circuit behaviour. SPICE was developed at the Electronics Research Laboratory of the University of California, Berkeley, by Laurence Nagel, under the direction of his research advisor, Prof. Donald Pederson.
SPICE source files are commonly referred to as "netlists", although they are sometimes known as "decks", with each line in the file called a "card". A netlist file is a plain ASCII text file containing multiple lines of text, each line describing either a circuit component or a special SPICE command. Circuit architecture is specified by assigning numbers to each component's connection points in each line, with connections between components designated by common numbers. SPICE always assigns a positive reference mark to the first node and uses the passive sign convention to assign the current reference.
A SPICE input file, or source file, consists of three parts: data statements, control statements, and output statements. Data statements describe the components and their interconnections, while control statements tell SPICE what type of analysis to perform on the circuit. Output statements specify what outputs are to be printed or plotted. SPICE combines operating point solutions, transient analysis, and various small-signal analyses with the circuit elements and device models needed to successfully simulate many circuits.
The output of a SPICE program is one or more graphs of currents, voltages, and other electrical quantities or is saved in a data file. All output values provided by SPICE are displayed in scientific notation. SPICE output can be modified to suit formatting needs and either saved to disk or printed on paper.

SPICE's applications beyond electronics
SPICE, an acronym for Simulation Program with Integrated Circuit Emphasis, is a circuit design software that can be used to simulate the electrical behaviour of analog or mixed signal circuits. SPICE was developed by the University of California, Berkeley in 1973 as open-source software. While SPICE is a valuable tool for electronics applications, its utility extends beyond electronics into various other fields.
One notable application of SPICE is in the food and pharmaceutical industries. SPICE's electrostatic technology has been leveraged by leading food processors worldwide to improve the application of flavourings, coatings, powders, additives, vitamins, spices, and oils. This technology enhances the efficiency of these processes while maximising flavour and reducing costs.
SPICE also finds utility in education and experimentation. It serves as a valuable tool for learning about electronics and circuit design, providing a "virtual" breadboard for experimentation. With SPICE, users can modify circuit parameters and immediately observe the effects, eliminating the need for expensive equipment and time-consuming physical circuit construction. This makes it an excellent resource for students and hobbyists to gain a deeper understanding of circuit behaviour.
Additionally, SPICE can be applied in the development of alternative energy systems. For example, it can be used to simulate and optimise the performance of solar panels, wind turbines, and other renewable energy technologies. By using SPICE simulations, engineers can model complex interactions and optimise system designs before physical implementation, reducing costs and accelerating the development process.
Furthermore, SPICE has applications in the field of robotics and automation. It can be used to simulate and test control systems, sensor networks, and other electronic components integral to robotic systems. By using SPICE simulations, roboticists can fine-tune their designs, predict potential issues, and optimise the performance of their creations. This virtual testing environment enhances the development process, reducing the need for costly physical prototypes.
