The process step with the longest execution time includes building the hardware system and the FPGA binary to run on AMD devices. Build time is also affected by the target device and the number of compute units instantiated onto the FPGA fabric. Therefore, it is useful to estimate the performance of an application without needing to build it for the system hardware.

The System Estimate report provides estimates of FPGA resource usage and the estimated frequency at which the hardware accelerated kernels can operate. The report is automatically generated for hardware emulation and system hardware builds. The report contains high-level details of the user kernels, including resource usage and estimated frequency. This report can be used to guide design optimization.

You can also force the generation of the System Estimate report with the following option:

v++ .. --report_level estimate

An example report is shown in the figure:
