In the hardware design example, the reset, status, and control signals from packet clients, F-Tile Ethernet Multirate Intel® FPGA IP, and F-Tile Dynamic Reconfiguration Suite Intel® FPGA IP in the example design are connected to In-System Sources and Probes IPs (ISSP). The hardware test scripts open service to the ISSP to read and drive the values. A JTAG host is instantiated to access the Avalon® memory-mapped interfaces.

The hardware design example executes the dynamic reconfiguration transition process, check the DUT IP status, clear the MAC statistics before sending 16 packets, and lastly display the MAC statistics.

Hardware Flow for Design Example:

The hardware test design contains a hwtest subdirectory that contains .tcl scripts for dynamic reconfiguration.
  1. Open System Console and navigate to the hwtest directory.
    cd hwtest
  2. Run the script. The script performs the dynamic reconfiguration steps and starts the packet client interface for the different datarates.
    source main_script.tcl
  3. Analyze the results. Successful run will display Test <ftile_eth_dr_test> Passed at System Console.
