simulated in Multicap, they will give you an idea of how such a circuit will function when
prototyped.
However, when a “real” component is referred to in this guide, it corresponds to a real,
purchasable component with values that include footprints and package type for use in PCB
layout programs, like Ultiboard.
“Virtual” components, however, give you a means to experiment with a specific component’s
parameters early in the design process. Once you have determined the desired parameters, you
can replace the “virtual” component with a “real” component. Real components must be
replaced in order to provide alternate values (e.g., to substitute a 1kOhm resistor for a
3MOhm resistor).
For real components, the tab looks like this:
