Document Table of Contents For Signal Tap Logic Analyzer

The Signal Tap logic analyzer requires both logic and memory resources. The number of logic resources used depends on the number of signals tapped and the complexity of the trigger logic. However, the amount of logic resources that the Signal Tap logic analyzer uses is typically a small percentage of most designs.

A baseline configuration consisting of the SLD arbitration logic and a single node with basic triggering logic contains approximately 300 to 400 Logic Elements (LEs). Each additional node you add to the baseline configuration adds about 11 LEs. Compared with logic resources, memory resources are a more important factor to consider for your design. Memory usage can be significant and depends on how you configure your Signal Tap logic analyzer instance to capture data and the sample depth that your design requires for debugging. For the Signal Tap logic analyzer, there is the added benefit of requiring no external equipment, as all of the triggering logic and storage is on the chip.
