Besides the ebfm_cfg_rp_ep procedure in altpcietb_bfm_configure, routines to read
and write endpoint configuration space registers directly are available in the
altpcietb_bfm_rdwr VHDL package or Verilog HDL include file. After the
ebfm_cfg_rp_ep procedure is run the PCI Express I/O and Memory Spaces have the
layout as described in the following three figures. The memory space layout is
dependent on the value of the addr_map_4GB_limit input parameter. If
addr_map_4GB_limit is 1 the resulting memory space map is shown in
Figure 15–7. Memory Space Layout—4 GByte Limit
