5.9.6. Monitor FPGA Resources Used by the Signal Tap Logic Analyzer

The Signal Tap Logic Analyzer has a built-in resource estimator that calculates the logic resources and amount of memory that each logic analyzer instance uses. Furthermore, because the most demanding on-chip resource for the logic analyzer is memory usage, the resource estimator reports the ratio of total RAM usage in your design to the total amount of RAM available, given the results of the last compilation. The resource estimator provides a warning if a potential for a “no-fit” occurs.

You can see resource usage (by instance and total) in the columns of the Instance Manager pane of the Signal Tap Logic Analyzer Editor. Use this feature when you know that your design is running low on resources.

The logic element value that the resource usage estimator reports may vary by as much as 10% from the actual resource usage.
