Using Capture to prepare for simulation

Capture is a design entry program you need to prepare

your circuit for simulation. This means:

• placing and connecting part symbols,

• defining component values and other attributes,

• defining input waveforms,

• enabling one or more analyses, and

• marking the points in the circuit where you want to

see results.

Capture is also the control point for running other

programs used in the simulation design flow.

What is the Stimulus Editor?

The Stimulus Editor is a graphical input waveform editor

that lets you define the shape of time-based signals used

to test your circuit’s response during simulation. Using

the Stimulus Editor, you can define:

•

analog stimuli with sine wave, pulse, piecewise linear,

exponential pulse, single-frequency FM shapes

The Stimulus Editor lets you draw analog piecewise linear

stimuli by clicking at the points along the timeline that

correspond to the input values that you want at

transitions.
