2.2. Reviewing the Summary Report

The Summary Report gives you a quick overview of the results of compiling your design including a summary of each kernel in your design and a summary of the estimated resources that each kernel in your design uses.

The Summary report is divided into the following sections based on the order of compilation:
  • Compile Info
  • Kernels Summary
  • Clock Frequency Summary
  • System Resource Utilization Summary
  • Quartus Fitter Resource Utilization Summary
  • Compile Estimated Kernel Resource Utilization Summary
  • Warnings Summary

Compile Info

The Compile Info section shows general information about the compile including the following items:
  • Name of the project
  • Target FPGA family, device, and board
  • Intel® Quartus® Prime version
  • Intel® FPGA SDK for OpenCL™ Offline Compiler version
  • The date and time at which the reports were generated

Kernels Summary

The Kernels Summary lists each kernel in your design, and some information about each of the kernels, including the following items:
  • Line number in the source code
  • Whether the kernel is an NDRange or a single work-item kernel
  • Whether the autorun attribute is used
  • The required workgroup size for the kernel
  • The number of compute units
When you select a kernel in the list, the Details pane shows additional information about the kernel:

Clock Frequency Summary

After you compile your design with Intel® Quartus® Prime software, the Clock Frequency Summary shows the following:
  • Quartus Fitter Clock Frequency
  • Compiler Target Frequency (MHz)
  • Compiler estimated frequency (MHz)

The Quartus Fitter clock frequency is the maximum clock frequency that can be achieved for the design. When the compiler estimates a lower frequency than the targeted frequency, the frequency value is highlighted in red.

Both the Kernels Summary and Clock Frequency Summary displays the target clock frequency applied at the source on the kernel. When the values of the source is different than the compilation flag you applied, the Clock Frequency Summary Compiler Target Frequency shows “Various” instead of reporting a number.

System Resource Utilization Summary

This displays a summary of device, static partition, kernel system total usage and total estimate of the resources used including ALMs, RAMs and DSPs. The device utilization and static partition constants are grayed out to indicate that you cannot change them in your design since these numbers map to the device datasheet and BSP, respectively.

Quartus Fitter Resource Utilization Summary

After you compile your design with Intel® Quartus® Prime software, this section is populated with the compilation results. The Quartus Fit Resource Utilization Summary section shows the total resource utilization both for the entire design, and for the device.

Compile Estimated Kernel Resource Utilization Summary

The Estimated Resource Usage section shows a summary of the estimated resources used by each kernel in your design, as well as the estimated resources used for all channels, estimated resources for the global interconnect, constant cache, and board interface.

Warnings Summary

The Warnings Summary section shows some of the compiler warnings generated during the compilation.
