7.2. Endpoint Testbench
The example design and testbench are dynamically generated based on the configuration that you choose for the F-Tile IP for PCIe. The testbench uses the parameters that you specify in the Parameter Editor in Intel® Quartus® Prime.
The top-level of the testbench instantiates the following main modules:
- altpcietb_bfm_rp_gen4_x16.sv —This is the Root Port PCIe* BFM.
//Directory path <project_dir>/pcie_avst_f_0_example_design/pcie_ed_tb/ip/pcie_ed_tb/dut_pcie_tb_ip/intel_pcie_ftile_tbed_<ver>
- pcie_ed_dut.ip: This is the Endpoint design with the parameters that you specify.
//Directory path <project_dir>/pcie_avst_f_0_example_design/ip/pcie_ed
- pcie_ed_pio0.ip: This module is a target and initiator of transactions for the PIO design example.
//Directory path <project_dir>/intel_pcie_ftile_ast_0_example_design/ip/pcie_ed
In addition, the testbench has routines that perform the following tasks:
- Generates the reference clock for the Endpoint at the required frequency.
- Provides a PCI Express reset at start up.
