5.3.6. Capture Data to a Specific RAM Type

You have the option to select the RAM type where the Signal Tap Logic Analyzer stores acquisition data. Once you allocate the Signal Tap Logic Analyzer buffer to a particular RAM block, the entire RAM block becomes a dedicated resource for the logic analyzer.

RAM selection allows you to preserve a specific memory block for your design, and allocate another portion of memory for Signal Tap Logic Analyzer data acquisition.

For example, if your design has an application that requires a large block of memory resources, such as a large instruction or data cache, you can use MLAB, M512, or M4k blocks for data acquisition and leave M9k blocks for the rest of your design.

To specify the RAM type to use for the Signal Tap Logic Analyzer buffer, go to the Signal Configuration pane in the Signal Tap window, and select one Ram type from the drop-down menu.

Use this feature only when the acquired data is smaller than the available memory of the RAM type that you selected. The amount of data appears in the Signal Tap resource estimator.
