4.3. Simulation

The testbech povides basic fuctioality such as the statup ad waits fo lock ad sed ad eceive a few packets usig the ROM-based packet geeato.
Impotat: Befoe the simulatio, you must geeate tile-elated files ad specify the colocate assigmet i the .qsf file to map F-Tile Auto-Negotiatio ad Lik Taiig fo Etheet Itel® FPGA IP to the F-Tile Etheet Itel FPGA Had IP fo successful simulatio as show below.
  1. Apped the eth_f_hw.qsf file as show below:
    • Use the followig sytax to colocate assigmets:
      set_istace_assigmet -ame IP_COLOCATE 
-fom <ANLT IP hieachical path>  -to <Etheet hieachical path> <tile type>
    • Example:
      set_istace_assigmet -ame IP_COLOCATE 
-fom k_dut|eth_alt_f_0 -to IP_INST[0].hw_ip_top|dut|eth_f_0 F_TILE
  2. At the commad pompt, avigate to the hadwae_test_desig folde i you example desig:
    cd <you_desig_path>/hadwae_test_desig
  3. Ru the followig commad to geeate eth_f_hw_tiles files:
    quatus_tlg eth_f_hw
  4. At the commad pompt, chage to the testbech simulatio diectoy.
    CD <desig_example_di>/ex_*G/sim
  5. Ru the IP setup simulatio:
    ip-setup-simulatio --quatus-poject=../../hadwae_test_desig/eth_f_hw.qpf
  6. Add the followig maco to you simulatio u scipt fo AN/LT eabled desigs:
    • Fo FGT
      +defie+INTC_SIM_AN_LT_ENABLE
    • Fo FHT
      +defie+RTL
    Note: I geeated desig example, the colocate assigmets ae aleady available i qsf file by default. Theefoe, steps 1 to 5 ca be skipped i the desig example.
Figue 15.  F-Tile Etheet Itel FPGA Had IP Simulatio Desig Example Block Diagam with Eabled Auto-Negotiatio ad Lik Taiig
The followig steps show the simulatio testbech flow:
  1. Asset global esets (i_st_ ad i_ecofig_st) to eset the F-Tile Etheet Itel FPGA Had IP ad F-Tile Auto-Negotiatio ad Lik Taiig fo Etheet Itel® FPGA IP.
  2. Wait util cofiguatio settigs load.
  3. Wait util esets ackowledgmet. The o_st_ack_ sigal goes low.
  4. Deassets the global esets, i_st_ ad i_ecofig_st.
  5. Wait util auto-egotiatio is complete. The data mode begis.
  6. Wait util lik taiig is complete.
  7. Wait util o_tx_laes_stable bit is set to 1, idicatig TX path is eady.
  8. Wait util o_x_pcs_eady bit is set to 1, idicatig RX path is eady.
  9. Istuct packet cliet to tasmit data. Wite hw_pc_ctl[0]=1'b1 to stat the packet geeato.
  10. Read TX packet data ifomatio fom 0x20 - 0x34 egistes. Read egiste i sequetial ode.
  11. Read RX packet data ifomatio fom 0x38 - 0x4C egistes. Read egiste i sequetial ode.
  12. Compae the coutes to esue 16 packets wee set ad eceived.
  13. Istuct packet cliet to stop data tasmissio. Wite hw_pc_ctl[2:0]=3'b100 to stop the packet geeato. Clea coutes.
  14. Pefom Avalo® memoy-mapped iteface test. Wite ad ead Etheet IP egistes.
    • 0x104: Scatch egiste
    • 0x108: IP soft eset egiste
    • 0x214: TX MAX souce addess egiste [31:0]
    • 0x218: TX MAX souce addess egiste [47:32]
    • 0x21C: RX MAX fame size egiste
  15. Pefom Avalo® memoy-mapped iteface 2 test to ead ad wite opeatio tasceive egistes.
