Overview of Electronic Circuit Simulators
Electronic circuit simulators use mathematical models to simulate the behavior of electronic circuits. These models take into account the characteristics of various components, such as resistors, capacitors, inductors, and semiconductors, to predict the circuit’s response to different inputs and operating conditions. Simulators can be used to analyze circuit performance, identify potential issues, and optimize designs before physical prototypes are built.
SPICE (Simulation Program with Integrated Circuit Emphasis)
SPICE is one of the most widely used electronic circuit simulators. It was developed in the 1970s at the University of California, Berkeley, and has since become an industry standard. SPICE can simulate a wide range of circuits, from simple analog circuits to complex digital systems. It is available in various forms, including open-source and commercial versions, such as Ngspice and PSPICE.
