Schematics to Prepare for

Simulation

Schematics 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.

Schematics 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, and

• digital stimuli that range from simple clocks to complex

pulse patterns and bus sequences.

The Stimulus Editor lets you draw analog piecewise linear and

all digital stimuli by clicking at the points along the timeline that

correspond to the input values that you want at transitions.
