The following table describes the commands found in the Simulate menu.

Runs/resumes the simulation of the active design. Running a simulation initializes the circuit, performs the circuit simulation and displays the results on the instrument or grapher.
Pauses the simulation.
Stops the simulation.
Analyses and simulation
Displays the Analyses and Simulation dialog box.
Places a Multimeter, which is used to measure AC or DC voltage or current, resistance, or decibel loss between two nodes in a circuit.
Instruments»Function generator
Places a Function Generator. This is a voltage source that supplies sine, triangular or square waves.
Places a Wattmeter, which provides the combined functions of a voltmeter and an ammeter. This instrument measures the magnitude of the active power, that is, the product of the voltage difference and the current flowing through the current terminals in a circuit.
Places a dual-channnel Oscilloscope. This instrument displays the magnitude and frequency variations of electronic signals. It can provide a graph of the voltage of one or two signals over time, or allow comparison of one waveform to another.
Instruments»Four channel oscilloscope
Places a Four Channel Oscilloscope.
Instruments»Bode plotter
Places a Bode Plotter, which produces a graph of a circuit’s frequency response. This is useful for analyzing filter circuits.
Instruments»Frequency counter
Places a Frequency Counter.
Instruments»Word generator
Places a Word Generator, which sends digital words or patterns of bits into circuits as a bit stream.
Instruments»Logic analyzer
Places a Logic Analyzer, which displays the levels of up to 16 digital signals in a circuit. This instrument is used for fast data acquisition of logic states and advanced timing analysis to help design large systems and carry out troubleshooting.
Instruments»Logic converter
Places a Logic Converter. This instrument can be attached to a circuit to derive the truth table or Boolean expression the circuit embodies, or to produce a circuit from a truth table or Boolean expression.
Instruments»IV analyzer
Places an IV Analyzer, which is used to measure current-voltage curves.
Instruments»Distortion analyzer
Places a Distortion Analyzer. A typical Distortion Analyzer provides distortion measurements for audio signals in the range of 20 Hz to 100 KHz.
Instruments»Spectrum analyzer
Places a Spectrum Analyzer, which is used to measure frequency versus amplitude.
Instruments»Network analyzer
Places a Network Analyzer. This is used to measure the scattering parameters (or S-parameters) of a circuit, commonly used to characterize a circuit intended to operate at higher frequencies.
Instruments»Agilent function generator
Places a simulated Agilent Technologies 33120A Function Generator on the workspace. This is a 15 MHz synthesized function generator with built-in arbitrary waveform capability.
Instruments»Agilent multimeter
Places a simulated Agilent Technologies 34401A Multimeter on the workspace. This is a 6 1/2-digit, high-performance digital multimeter.
Instruments»Agilent oscilloscope
Places a simulated Agilent Technologies 54622D Oscilloscope on the workspace. This is a 2-channel +16 logic channels, 100-MHz bandwidth oscilloscope.
Instruments»LabVIEW instruments
Displays a number of LabVIEW instruments that you can place on the workspace.
Instruments»NI ELVISmx instruments
Displays a number of NI ELVISmx instruments that you can place on the workspace.
Instruments»Tektronix oscilloscope
Places a simulated Tektronix TDS 2024 Oscilloscope on the workspace.
Instruments»Current probe
Places a “clamp-on” current probe on the workspace.
Mixed-mode simulation settings
Use to choose between optimizing either the accuracy or the speed of simulation when digital components are included in your design.
Probe settings
Displays the Probe Settings dialog box.
Reverse probe direction
Reverses the polarity of a selected Current Probe.
Locate reference probe
Highlights a selected probe’s corresponding Reference Probe.
NI ELVIS II simulation settings
Displays the Select instruments for simulation dialog box.
Opens the Postprocessor dialog box, which you use to combine the results of several analyses in different ways. To use the Postprocessor, you must have performed at least one analysis on your circuit.
Simulation error log/audit trail
Shows or hides the simulation log, which records all the events of a circuit simulation.
XSPICE command line interface
Opens a window into which you can type Xspice commands.
Load simulation settings
Loads a set of simulation settings that you saved earlier.
Save simulation settings
Saves a set of simulation settings for later use.
Automatic fault option
Applies faults to randomly selected components in the design. You choose the number of faults (either in total, or the number of each type of fault) to be applied.
Clear instrument data
Clears simulation data from instruments like the oscilloscope. Does not clear the Grapher.
Use tolerances
Select to use the component tolerances set in individual components during simulation.
