AXI Bridge for PCI Express (Vivado 2018.2) - The offsets in address editor do not match with the generated IP

描述

 

Version Found: v2.8 (Rev9)

Version Resolved and other Known Issues: See (Xilinx Answer 54646)

In a block design containing AXI Bridge for PCI Express IP, the offset addresses set in the address editor is not correctly reflected in the IP.  

If the following offsets are set in the address editor for BAR0, BAR1 and BAR2 respectively,

  • 0x50000000
  • 0x60000000
  • 0x70000000

the generated XCI for AXI Bridge for PCI Express IP will contain the following:

MODELPARAM_VALUE.C_AXIBAR_0 will be 0x50000000
MODELPARAM_VALUE.C_AXIBAR_1 will be 0x30000000
MODELPARAM_VALUE.C_AXIBAR_2 will be 0x40000000

C_AXIBAR_0 is correct but C_AXIBAR_1 and C_AXIBAR_2 values are not correct. They should be 0x60000000 and 0x70000000 respectively.
