Figure 1 shows the interface of Multisim. The highlighted red box is where the devices are located. With the Multisim V11.0, a lot more devices simulation are supported which includes PLC, and also some PIC16F microcontrollers.

Having devices is not sufficient to get data. Thus, Multisim includes various virtual instruments such as oscilloscope, multimeter and spectrum analyzer. Some of these instruments are based on instrument manufacturers such as Agilent and Textronix. Figure 2 shows the various instrument toolbar located at the right.

Below is an example of a Bar Graph Display of AC signal. The AC signal will be produced by the signal generator and the signal wil be measured by an oscilloscope. Additionally, the amplitude of the signal will determine the display of the Bar graph. Devices and virtual instrument can be easily selected from the device toolbar and the instrument. The devices and instrment which are selected is put into the layout and connected.

Based on Figure 4, the oscilloscope which is used is from agilent. Besides that, the model also have the same layout of the original model.

The signal generator which is used here is also from agilent which has the same layout as the original hardware.

Figure 6 shows the simulation. During simulation, you can manipulate the virtual instruments and view the results similar to what is shown on the oscilloscope and other output devices on the layout.

Conclusion
With this simulation software, circuit design and testing can be simplified as real hardware is not required. And the analysis can be done remotely with other engineers and designers for their recommendations and opinions.
