Example : Simulation

Step 3 : Select and place components


Note : You do not have to place the components exactly the same way as seen in the example images. As long as you connect them correctly, you can always move a component to some other location in the same schematic.

1. Pick up and place the rest of the components required for the simulation.

The remaining components are in the "NCSU_Analog_Parts" library. Change your library from "tutorial" to "NCSU_Analog_Parts". Refer to the previous example (step 3 :"Changing the library in the Component Browser window") to see how you can change the source library.

We placed all the necessary components for this schematic.

2. Why did we put these components into this schematic ?

You can think of this procedure (creating a new schematic and placing these components into the new schematic) as being analogous to building a "test-bench" for the circuit you designed. As in the real test-bench case, you must build a simple test set-up (consisting of voltage sources, load devices, etc.) around your original circuit to measure its operation and its characteristics.
