Resolution
This is due to the PCI Express® Hard IP core was setting to Single DWord Completer mode with \'Single DW Completer\' option is checked.
To simulate in Single DWord Completer mode, user need to open the driver file: altpcietb_bfm_driver_avmm.v and edit to:
parameter RUN_TGT_MEM_TST = 1;
parameter RUN_DMA_MEM_TST = 0;
parameter AVALON_MM_LITE = 1;
