Document Table of Contents Data Log Pane

The Data Log pane displays all Signal Tap configurations and data capture results that a single .stp file stores.
  • To save the current configuration or capture in the Data Log of the current .stp file, click Edit > Save to Data Log.
  • To automatically generate a log entry after every data capture, click Edit > Enable Data Log. Alternatively, enable the box at the top of the Data Log pane.

The Data Log displays its contents in a tree hierarchy. The active items display a different icon.

Table 24.  Data Log Items
Item Icon Contains one or more Comments
Unselected Selected
Instance Signal Set The top-level for a particular Signal Tap instance.
Signal Set Trigger The Signal Set changes whenever you add a new signal to a Signal Tap instance. After a change in the Signal Set, you need to recompile.
Trigger Capture Log A trigger changes when you change any trigger condition. Some of these changes do not require recompilation.
Capture Log   Contains captured sample data for this particular trigger configuration, for the particular signal set for this particular Signal Tap instance. There can be multiple capture logs for a particular setup if you run the logic analyzer multiple times, as Simple Data Log shows.

The name on each entry displays the wall-clock time when the Signal Tap logic analyzer triggers, and the time elapsed from start acquisition to trigger activation. You can rename entries.

To switch between configurations, double-click an entry in the Data Log. As a result, the Setup and Data tabs update to display the active signal list, trigger conditions, or specified captured data.

Figure 88. Simple Data LogIn this example, the Data Log displays one instance with three signal set configurations, two trigger condition setups, and three different captured data sets.
