Adding and Defining Stimulus
The Stimulus Editor is a utility that enables you to set up
and verify the input waveforms for a transient analysis.
You can create and edit voltage sources, current sources,
and digital stimuli for your circuit. Menu prompts guide
you to provide the necessary parameters, such as the rise
time, fall time, and period of an analog repeating pulse, or
the complex timing relations with repeating segments of a
digital stimulus. Graphical feedback enables you to verify
the waveform.
Placing Stimulus Sources
Stimulus sources come from the source.slb symbol
library and are one of:
• VSTIM—voltage stimulus source for transient
analysis
• ISTIM - current stimulus source for transient analysis
• DIGSTIM - digital stimulus source
You can place any of these sources by typing the name of
the source in the Get Recent Part list box on the toolbar.
The AC and DC sources are VAC and VDC, and can be
placed similarly.
1 Double-click in the Get Recent Part list box and type
the name of the source.
2 Press R and click to place the source.
3 Right-click to stop placing sources.
