11.11.4. Opening the Efficiency Monitor Toolkit

The Efficiency Monitor GUI runs on the System Console. You can launch the System Console from the Tools menu in the Intel® Quartus® Prime software.

Connecting the Efficiency Monitor

  1. Compile a design with an Efficiency Monitor, as described in Enabling the Efficiency Monitor in a Design Example .
  2. Program the .sof file onto a device.
  3. Launch the System Console—either through the Intel® Quartus® Prime software, or directly from the command line.
  4. Load the .sof file of your design.
  5. Select the emif_effmon toolkit instance.
  6. Select EMIF Efficiency Monitor Toolkit in the Details section of the Toolkit Explorer in the System Console.
  7. Click Open Toolkit to launch the Efficiency Monitor toolkit.

Performance Report

The Performance Report tab displays efficiency as a percentage, and the read latency report.

Figure 225. Performance Report Tab
The reported values are calculated using values in the status registers, as follows:
  • Minimum Read Latency = EFFMON_RDLAT_MIN
  • Maximum Read Latency = EFFMON_RDLAT_MAX
