Simulation is a design analysis, which replaces design symbols with their Simulation models and provides a detailed analysis of their behavior. For Simulating a designed circuit, the model of the real circuit is created taking all factors into consideration, and the appropriate inputs are given. Then the outputs at each level are checked and corrections or modifications are made.

For Simulating a designed circuit, the model of the real circuit is created taking all factors into consideration, and the appropriate inputs are given.

The simulator now supports simulation of hierarchical databases. In addition to that, two new analysis has been introduced in Mixed mode simulator that assist end users to design the circuit precisely. Monte Carlo analysis is used to calculate component parameter values for a given output at a given instant of time. Sensitivity analysis points out the most sensitive component to a particular parameter such as voltage, current, etc.
During simulation all factors are taken into consideration and a model of the real circuit is created and the inputs are given accordingly. Then the outputs at each level are checked and corrections or modifications, if any, are made.
There are a number of algorithms used universally to simulate a circuit. The Mixed-Mode Simulator is one of the best tools used. It can simulate analog, digital as well as a combination of analog-digital circuits. It is a de facto that an analog simulator equipped with a logic simulation engine that models the digital parts of a circuit during the Transient Analysis run. The commonly used functions by the simulator are: Bias point calculation, Transient analysis, Parameter sweep analysis, DC Sweep Analysis, AC Sweep Analysis, Monte Carlo Analysis, Sensitivity Analysis, Preprocessing pass.
