Using Replay Analysis

Replay analysis provides the ability to replay plots and symbol animation at different speeds without the need for re-simulation. It also provides the ability to drag the slider to any intermediate point on the simulation time line with dynamic plot update to that point. You can also use replay analysis to debug state graphs and other intermediate signal changes.

Simulation data must be present, or the design must have been analyzed before running replay analysis.

The following schematic objects are updated to their current simulation state during analysis replay.

To replay an analysis:

Select Twin Builder > Replay Analysis, click , or in the Project tree, right-click the analysis and select Replay Analysis. The Replay Analysis time line appears in the progress window.

Perform the action you want using the following controls.

Control	Action
	Click to move 10 frames backward. You can also press Page Up.
	Click to move one frame backward.
	Click to play the simulation. If you have moved the slider, the simulation starts at that position. After you click this button, it changes to Pause. Click Pause to pause the simulation. If you click the slider after the replay has finished, the button displays Replay. Click Replay to replay the simulation.
	Click to move one frame forward.
	Click to move 10 frames forward. You can also press Page Down.
	Drag the slider to adjust the speed of the replay.
	Click to manually enter a replay start time.
	Click to go to the manually entered replay start time.
	Enter a replay start time.

To manually select replay start time:

Click GoTo.
Enter the desired replay start time.
Click Apply.

You can also drag the slider to a position and click Play.

In addition to using the buttons, click the slider and use defined keys for the following actions.

Key	Action
left arrow	Press to move one data point backward.
right arrow	Press to move one data point forward.
Home	Press to move to the start point.
End	Press to move to the end point.
PgUp	Press to move 10 frames backward.
PgDn	Press to move 10 frames forward.

Click to close the Replay Analysis dialog box.

Note:

You can simultaneously replay more than one analysis as long as the analyses are not part of the same design. If you replay another analysis of the same design, the active panel closes before the new one starts.
