ebfm_barrd_wait seems to stall about PCIe_DDR2_ref_dgn_arria2gx.qar simulation

Hi All,

I downloaded the PCIe demo PCIe_DDR2_ref_dgn_arria2gx.qar; it seems to work well and the documentation is quite good.

However, when I try to run the testbench in altpcietb_bfm_driver_chaining.v, it seems to get stuck in ebfm_barrd_wait. Basically, it sits waiting for an acknowledgement from the DDR memory, which doesn't seem to come back.

I'm just running the testbench out of the box, in Altera's modelsim. Any thoughts on this? I can give more specific info if you think you can help.
