Lock Mode
Allows you to select different lock modes that control the kind of changes you can make in the SignalTap II Logic Analyzer. This feature helps prevent inadvertent changes to the design that require recompilation. The following lock modes are available:
- Allow all changes— Allows you to make all changes to SignalTap II File (.stp) Definition.
- Allow trigger condition changes only— Allows you to change only the trigger conditions in a SignalTap II File. You can change logic conditions, enable and disable trigger conditions, enable and disable the trigger input and trigger output signals, and change the trigger position, buffer acquisition mode, and segment size. You cannot switch between basic and advanced trigger conditions when you turn on lock mode.
Important: Important: When you select Allow trigger condition changes only in
the Setup tab in the
SignalTap II Logic Analyzer, all editable fields in the
Custom Trigger Flow tab are
disabled and the runtime-modifiable values become underlined with
hyperlinks. When you click one of the hyperlinks, a shortcut menu
allows you to select a different value. You cannot edit the
remaining text.
