The amplitude and frequency you put in earlier for transient analysis are ignored. Alternately, you can put AC in the magnitude box and 1 in the phase block. Now go to the menu Simulate / Edit Simulation Command and the AC Analysis tab. You’ll want to play with “type of sweep”, but Octave is fine for now.

transient, steady state, and frequency domain analyses. Existing SPICE decks created for SPICE-3 can be easily modified to run under HSPICE, or can be rewritten to take advantage of features not available in SPICE-3. HSPICE generally has better convergence than SPICE-3 and, because it is a commercial product (from Meta-Software), is better ...
Use Transient analysisto see your waveforms in time domain, see if they are distorted, run spectrum (FFT) analysis, figure actual impedances and powers delivered and dissipated. Use AC analysis to see response versus frequency for amplifiers, attenuators, filters (active or passive) and so on. Response is in dB relative to 1 volt on the source.

May 23, 2019 · Learn multiple ways to simulate noise sources—for both transient and noise analysis—in LTspice. In a previous article, we discussed some examples of modeling noise in LTspice . Now, let's discuss how to build noise sources in the frequency domain using noise analysis and in the time domain using transient analysis.
Dec 20, 2019 · For my application I need to sweep a current sink as explained in the "LTspice: Using .MEAS and .STEP Commands to Calculate Efficiency" article where the author r eplaces the resistive load with a independent current source and defines the value using a global variable {Iload} which is what I was referring to in my original question.

3. DC sweep. In DC analysis, the X axis will be a DC voltage other than 'time' in transient analysis. In the following schematic, the circuit ran a DC sweep for the input voltage from -2 V to 5 V. The X axis will be the 'sweep' of the DV values for Vin, the Y axis is the voltages that affected by the input.

A makefile keeps the directories clean of useless files and can automatically graph the results. Check out the Makefile that I use (Note GetTran and GetAc are scripts that remove AC and Transient analysis data from the .lis file to graph in Matlab). ----Return to Index---- LTspice is designed from the ground up to produce fast circuit simulations, but there is margin in some simulations to increase the speed. Note, there may be trade-offs in accuracy using the methods described here. For further details on any of these approaches, please refer to the LTspice Help File (F1). To measure the effects of your changes, rev LTSpice is capable of several types of simulation, but today we'll be covering just two:.tran and.AC, which stand for Transient and AC Sweep analysis, respectively. From my own experience, these are the two most commonly-used simulation forms and garner some valuable info. Open the Simulate menu and go to Edit Simulation Cmd

Another excellent feature of the DC sweep in LTspice, is the ability to do a nested sweep. A nested sweep allows you to run two simultaneous sweeps to see how changes in two different DC sources will affect your circuit. Electronics Simulating a switch mode power supply - LTspice 2.1 Resistor-capacitor low pass filter We begin with a circuit that you may be familar with, to check that we can reproduce its behaviour. Use LTspice (or other simulator) to draw the circuit shown in Fig. 1. Figure 1: R-C Low pass filter circuit Simulation is an essential link in the process of PCB design. PSpice is a simulator provided by OrCAD PCB design software. Coupled with work flow of OrCAD Capture, PSpice provides a fast trailer prior to board design in order to increase PCB manufacturing efficiency and ensure the final performance of PCBs.
