E.3. Integrate Avery BFMs (Root Complex)

P-Tile supports serial mode connection only. The Avery Root Complex must instantiate a standalone BFM PHY to interface with the P-Tile PCIe Hard IP. The Avery BFM replaces the default Root Port BFM (dut_pcie_tb) in the P-Tile PCIe PIO example design testbench. The following diagram is a new top-level testbench, pcie_ed_tb.sv, that includes the Avery BFM.

Figure 99. Integrating the Avery BFM (Root Complex) and the PCIe Example Design

To include the Avery BFM, use the pcie_ed_tb.sv provided in the .zip file that you download or modify the example design top-level testbench as follows:

  1. Open the example design top-level testbench file <example design folder>/pcie_ed_tb/pcie_ed_tb/sim/pcie_ed_tb.v.
  2. Import Avery BFM packages by adding the following lines below the `timescale statement:
    • import avery_pkg::*;
    • import apci_pkg::*;
    • import apci_pkg_test::*;
    • `include "apci_defines.svh"
  3. Include the Avery BFM by adding the following line above the example design Root Port BFM (dut_pcie_tb).
    • `include "./../../apci_top_rc.sv"
  4. Comment out the example design Root Port BFM (dut_pcie_tb).
  5. Save the file and rename it to pcie_ed_tb.sv.
  6. Open <example design folder>/pcie_ed_tb/pcie_ed_tb/sim/common/vcs_files.tcl. Find and replace pcie_ed_tb.v with pcie_ed_tb.sv.

For details, refer to apci_top_rc.sv, pcie_ed_tb.sv, and vcs_files.tcl files available in the .zip file that you download.
