CHAPTER 12: DEBUGGING
USING THE SIGNALTAP II LOGIC ANALYZER
ALTERA CORPORATION INTRODUCTION TO QUARTUS II ■ 201
Figure 4. Advanced Triggers Tab of the SignalTap II Window
You can configure the logic analyzer with up to ten trigger levels,
helping you to view only the most significant data. You can specify four
separate trigger positions: pre, center, post, and continuous. The trigger
position allows you to specify the amount of data that should be
acquired before the trigger and the amount that should be acquired
after the trigger in the selected instance.
Segmented mode allows you to capture data for periodic events
without allocating a large sample depth by segmenting the memory
into discrete time periods.
■ Incremental Routing: The incremental routing feature helps to shorten
the debugging process by allowing you to analyze post-fitting nodes
without performing a full recompilation.
Before using the SignalTap II incremental routing feature, you must
perform a smart compilation by turning on Automatically turn on
smart compilation if conditions exist in which SignalTap II with
