Proteus ISIS software program

Computer simulation involves designing a model of an actual or theoretical physical system, executing the model on a digital computer and analysing the execution output. An electronic simulator, such as ISIS, can be defined as a program that allows for the drawing of schematic circuits and through mathematical models libraries associated with devices, also permit the simulation of components behaviour in accordance with the global behaviour of the circuit. The software simulation often represent an important part of a development environment that provides important tools as routing software, PCB editor (ARES), a design rule checker and so on.

ISIS makes use of SPICE for the simulation. SPICE, an algorithm developed at University of California, Berkeley represents the core of software electronic simulation. Together with PCB editor tools, SPICE simulation has become the standard in electronics industry for speeding up large-scale production. Integrated Development Environments (IDEs) are required together with electronic circuit design tools for writing program codes to test and simulate the operation of the microcontroller before manufacture of the hardware prototype.
