Output instruments generate data to use as a signal source in simulation. Input instruments receive simulation data for display or processing. LabVIEW VIs can be input instruments, output instruments, or input/output instruments.
Multisim then uses that data as a signal source for circuit simulation.
VIs that you create using LabVIEW can take advantage of the full functionality of the LabVIEW development system, including data acquisition, instrument control, and mathematical analysis. Simulation-driven instruments have three distinctive views to each instrument, which allows for selection, placement, wiring, setting configuration, data visualization, and so on.Įxtend your simulation and analysis capabilities beyond the instrumentation in Multisim with the creation of custom VIs using the LabVIEW graphical development environment. With Multisim, you can place simulation-driven instruments from the Simulate»Instruments menu or directly from the Instruments toolbar as seen below. You can save instrument settings and simulation results with the circuit file and resize the faceplates of instruments to adjust to different screen resolutions and presentation modes.
When you press a button on an instrument, an appropriate simulation command is automatically issued and results are immediately displayed on that instrument's user interface. Simulation-driven instruments help you take advantage of the full power of simulation without having to be an expert in SPICE syntax. These simulation-driven instruments, like their real-world counterparts, are fully interactive so you can change their settings while running a simulation and instantly see new results.
In addition to the components and wires used to capture a circuit, NI Multisim software contains a variety of simulation-driven instruments that wire into the schematic just like you connect a real instrument on the bench.
