Calculating voltage bias with gaussian software

In в‘ , the definition tol = flat(0.05) is used Two types of random number are used the distributions of both are shown. A random number is used for tol to generate variation, and in this example the simulation is executed 300 times. The resistance value is written this can be written directly in the resistance value field when setting the resistance value. In this example, a simulation is performed of the resistance value (voltage/current) when a voltage is applied to a 100 О© resistor. гѓ»Case in which variations can be directly described for symbols Monte Carlo setting methods are also different depending on whether variations can or cannot be directly stated for resistors and other symbols. Methods for setting variations differ depending on the simulation type. Various methods are used, but in essence the variations mainly of the circuit elements that have the largest effect on the overall circuits are added. This is effective when the characteristics of the overall circuit are affected by multiple circuit elements. In a Monte Carlo simulation, simulations that reflect the variation in the different circuit elements are executed a number of times, and variation in the overall characteristics can be evaluated. There is variation in each individual component, and the sum of the variations of the components results in variation in the characteristics of the circuit.

For example, a resistor has a tolerance: the resistance value of a resistor that is nominally 100 О© with a precision of В±5% is between 95 О© and 105 О©.

Nearly all the components used to create actual circuits-resistors, capacitors, inductors, diodes, transistors, ICs, and so on-have characteristics with variations. Monte Carlo is a general term for methods using random numbers in simulations and numerical calculations. In this article, we explain the remaining function, Monte Carlo simulations. In the previous article we described SPICE simulation types and explained DC analysis, AC analysis, and transient analysis among the four types of analysis functions provided as standard.
