4.3. Simulation

The testbench provides basic functionality such as the startup and waits for lock and send and receive a few packets using the ROM-based packet generator.
Important: Before the simulation, you must generate tile-related files and specify the colocate assignment in the .qsf file to map F-Tile Auto-Negotiation and Link Training for Ethernet Intel® FPGA IP to the F-Tile Ethernet Intel FPGA Hard IP for successful simulation as shown below.
  1. Append the eth_f_hw.qsf file as shown below:
    • Use the following syntax to colocate assignments:
      set_instance_assignment -name IP_COLOCATE \
-from <ANLT IP hierarchical path>  -to <Ethernet hierarchical path> <tile type>
    • Example:
      set_instance_assignment -name IP_COLOCATE \
-from kr_dut|eth_anlt_f_0 -to IP_INST[0].hw_ip_top|dut|eth_f_0 F_TILE
  2. At the command prompt, navigate to the hardware_test_design folder in your example design:
    cd <your_design_path>/hardware_test_design
  3. Run the following command to generate eth_f_hw_tiles files:
    quartus_tlg eth_f_hw
  4. At the command prompt, change to the testbench simulation directory.
    CD <design_example_dir>/ex_*G/sim
  5. Run the IP setup simulation:
    ip-setup-simulation --quartus project=../../hardware_test_design/eth_f_hw.qpf
  6. Add the following macro to your simulation run script for AN/LT enabled designs:
    • For FGT
      +define+INTC_SIM_AN_LT_ENABLE
    • For FHT
      +define+RTL
    Note: In generated design example, the colocate assignments are already available in qsf file by default. Therefore, steps 1 to 5 can be skipped in the design example.

The following steps show the simulation testbench flow:
  1. Assert global resets (i_rst_n and i_reconfig_rst) to reset the F-Tile Ethernet Intel FPGA Hard IP and F-Tile Auto-Negotiation and Link Training for Ethernet Intel® FPGA IP.
  2. Wait until configuration settings load.
  3. Wait until resets acknowledgment. The o_rst_ack_n signal goes low.
  4. Deasserts the global resets, i_rst_n and i_reconfig_rst.
  5. Wait until auto-negotiation is complete. The data mode begins.
  6. Wait until link training is complete.
  7. Wait until o_tx_lanes_stable bit is set to 1, indicating TX path is ready.
  8. Wait until o_rx_pcs_ready bit is set to 1, indicating RX path is ready.
  9. Instruct packet client to transmit data. Write hw_pc_ctrl[0]=1'b1 to start the packet generator.
  10. Read TX packet data information from 0x20 - 0x34 registers. Read register in sequential order.
  11. Read RX packet data information from 0x38 - 0x4C registers. Read register in sequential order.
  12. Compare the counters to ensure 16 packets were sent and received.
  13. Instruct packet client to stop data transmission. Write hw_pc_ctrl[2:0]=3'b100 to stop the packet generator. Clear counters.
  14. Perform Avalon® memory-mapped interface test. Write and read Ethernet IP registers.
    • 0x104: Scratch register
    • 0x108: IP soft reset register
    • 0x214: TX MAX source address register [31:0]
    • 0x218: TX MAX source address register [47:32]
    • 0x21C: RX MAX frame size register
  15. Perform Avalon® memory-mapped interface 2 test to read and write operation transceiver registers.

Note: The simulation completion may take a longer time. To confirm the simulation is progressing successfully, verify the intermediate outputs from the System Console such as bringing the base and AN/LT IP out of resets, IP resetting sequence, Auto-negotiation and link training auto-connection completion, and others.
