5.3. Simulation

The testbench provides basic functionality such as the startup and wait for lock, sending and receiving of a few packets per each instantiated IP using the ROM-based packet generator.
Figure 16. Simulation Design Example Block Diagram with 2 instantiated F-Tile Ethernet Intel FPGA Hard IPs
The following steps show the simulation testbench flow:
  1. Assert global reset (i_rst_n) to reset each F-Tile Ethernet Intel FPGA Hard IP instance (IP instance).
  2. Wait until resets acknowledgment from all IP instances. The o_rst_ack_n signals go low.
  3. Deasserts the global reset.
  4. Wait until o_tx_lanes_stable bit is set to 1, indicating TX path is ready.
  5. Wait until o_rx_pcs_ready bit is set to 1, indicating RX path is ready.
  6. Repeat steps 4 and 5 to complete the reset sequence for all IP instances.
  7. Instruct packet client to transmit data. Write hw_pc_ctrl[0]=1'b1 to start the packet generator.
  8. Read TX packet data information from 0x20 - 0x34 registers. Read registers in a sequential order.
  9. Read RX packet data information from 0x38 - 0x4C registers. Read registers in a sequential order.
  10. Compare the counters to ensure 16 packets were sent and received.
  11. Instruct packet client to stop data transmission. Write hw_pc_ctrl[2:0]=3'b100 to stop the packet generator. Clear counters.
  12. Repeat steps 7 - 11 to simulate packet transfer for each of the instantiated IPs.
  13. Perform Avalon® memory-mapped interface test. Write and read Ethernet IP registers.
  14. Perform Avalon® memory-mapped interface 2 test to read and write operation transceiver registers.
  15. Repeat steps 13 and 14 for each instantiated IP in a sequential order.
The following sample output illustrates a successful simulation test run. 

---SRC IP sequence started -----
---SRC IP sequence TX completed -----
---SRC IP sequence RX completed -----
---Test    0;   ---Total     16 packets to send-----

------ALL   16  packets Sent out---
------------  16 packets Sent;    16 packets Received--------
------ALL   16  packets Received---
------TX/RX packet check OK---
