The basic root port BFM provides a VHDL procedure-based or Verilog
HDL task-based interface for requesting transactions that are issued to
the PCI Express link. The root port BFM also handles requests received
from the PCI Express link. See
port BFM.
The root port BFM consists of these main components:

IP Functional Simulation
BFM shared memory (altpcietb_bfm_shmem VHDL package or
Verilog HDL include file) — The root port BFM is based on the BFM
memory that is used for the following purposes:
