2.4.6.11.5. Signal Tap Trigger Flow Description Language

The Trigger Flow Description Language is based on a list of conditional expressions per state to define a set of actions.

To describe the actions that the logic analyzer evaluates when a state is reached, follow this syntax:

Syntax of Trigger Flow Description Language

state <state_label>:
	<action_list>
	if (<boolean_expression>)
		<action_list>
	[else if (<boolean_expression>)
		<action_list>]
	[else
		<action_list>]
  • Non-terminals are delimited by "<>".
  • Optional arguments are delimited by "[]".
  • The priority for evaluation of conditional statements is from top to bottom.
  • The Trigger Flow Description Language allows multiple else if conditions.
