Follow these steps to observe the throughput of the design:
In the Graph View, select the I/O tab and observe the Throughput column for each ports.
The output PLIO port (PLIO_fft_o) throughput shows the value 2307.08 MB/s. To get the throughput in samples per second, divided it by four because the data type used is cint16, which is four bytes in size. This gives a throughput value of 576.77 MSPS.
Close the Vitis Analyzer.
Optional: By running the make throughput command, it lists the throughput for the FIR and FFT output. This uses the custom python script which reads the time stamp from the output file and displays the value.
Enter the following command to analyze the throughput:
make throughput
Per the design requirement for design 1, the required sampling rate is 400 MSPS. The achieved sampling rate is ~576 MSPS.
After reviewing the reports, close the Vitis Analyzer.
