Understanding Capture Control

The Logic Analyzer core supports a capture control option. When you turn on this option in the debug profile, the Capture Setup tab becomes available during debugging.

The Capture Mode option selects which condition the Debugger evaluates before each sample is captured:

Always—Stores a data sample during a given clock cycle regardless of any capture conditions you set.
Basic—Only stores a data sample during a given clock cycle if the capture condition evaluates as true. Select this option to add nets and set capture conditions.

You can subdivide the capture data buffer into one or more segments. The Debugger automatically suggests a window depth depending on the number of segments you choose. Additionally, you can set the position of the trigger in the window.
