Used to sweep variables, including: temperature, voltages and currents from sources, resistances and conductivity. DC sweep - generates output like that of a curve tracer.DC Transfer function - (DC small signal analysis) calculates the DC input resistance, DC output resistance and DC gain, at each voltage node in the circuit.This circuit is then used to find the poles and zeros that satisfy the nominated transfer function. The dc operating point of the circuit is found and then linearized, small-signal models for all non-linear devices in the circuit are determined. Poles and Zeros of transfer function - used to determine the stability of a single input, single output linear system, by calculating the poles and/or zeros in the small-signal ac transfer function for the circuit.Operating Point - determines the dc operating point of a circuit, with inductors shorted and capacitors opened.

The simulator supports the following types of analyses: What can we Simulate using SPICE?Īltium's simulation technology is under active development, including the variety of supported models and model types (including Pspice & LTSpice), the underlying algorithms, and the available types of circuit analyses. This guide will cover not only the mechanisms for obtaining basic circuit characteristics, but also the features of circuit design for simulation, the process of adding models to circuit elements, and the description of the Netlist document and its application. Altium's Mixed Simulation (MixedSim) technology uses an improved core based on SPICE algorithms and is designed to simulate analog, digital or mixed analog-to-digital device electrical circuits.

SPICE (Simulation Program with Integrated Circuit Emphasis) was developed as an open-source software package, which has led to its broad popularity and continued development. And the results of these simulations can conveniently be grouped on one plot, they can use several axes, you can change the display color, take measurements directly from the plots, share the results with colleagues, and much more. The use of a simulation program makes it possible to analyze all modes of the device being designed without possible damage, to determine parameters and characteristics that are difficult to measure in real conditions, and to perform measurements that might otherwise require the use of expensive measurement equipment. However, it is impossible to imagine the design of even the simplest device without the capabilities that simulation offers. The jump from experimental methods to computer software simulation happened quite a long time ago. The main purpose of simulating the function of an electronic device is to represent and analyze the performance of the design. Simulation, what is it and why is it necessary?

This guide covers the basic principles of SPICE simulation, how to avoid mistakes, as well as lots of information on learning how to use the tool. The use of computer simulation makes it possible to experiment, obtain real circuit characteristics, evaluate possible risks in the device, and also achieve the implementation that best delivers the product's intended operational range and characteristics. Modern electrical circuit CAD systems combine the ability to simulate circuits that include both analog and digital devices. The most efficient and cost-effective option is the use of modern methods of mathematical simulation, using Computer-Aided Design (CAD) systems.
