The Signal Tap logic analyzer shows read and write activity in the system.

For more information about using the Signal Tap logic analyzer, refer to the Quartus® Prime Pro Edition User Guide: Debug Tools.

To add the Signal Tap logic analyzer, follow these steps:

  1. On the Tools menu click Signal Tap Logic Analyzer .
  2. In the Signal Configuration window next to the Clock box, click … (Browse Node Finder).
  3. Type the memory interface system clock in the Named box, for Filter select Signal Tap: presynthesis and click Search.
  4. Select the memory interface clock that is exposed to the user logic.
  5. Click OK.
  6. Under Signal Configuration, specify the following settings:
    • For Sample depth, select 512
    • For RAM type, select Auto
    • For Trigger flow control, select Sequential
    • For Trigger position, select Center trigger position
    • For Trigger conditions , select 1
