For the timing diagram editors, samples are just graphical constructs that do not have any effect on the timing of the waveforms. However, samples are used by TestBencher Pro and Reactive Test Bench Generation to indicate points that are to be watched during simulation. If you are adding samples for test bench generation, please read the sample chapters in those manuals. This section is only about making pretty looking samples.

Press the Sample button so that right clicks will add samples to the diagram.

sample_1

To attach a sample to a time, make sure no edges are selected, then right click on a waveform to add a sample.

sample_2

To attach a sample to an edge, select the control edge, then right click on the waveform to be sampled.

sample_3

To make a box sample, double click on a sample to open the Sample Properties dialog, and set the min and max values to define the box.

sample_4

Samples are also added to the Parameter Properties dialog.

sample_5

Change how the Sample looks:

Samples are parameters (just like delays, setups, and holds) so most all of the parameter editing techniques also work for samples. See 5.3 Display Settings for Parameters, 5.4 Drawing and Editing Parameters, 5.5 Hiding Parameters, and 5.6 Parameter Window.
