PCIe core simulation

I created a PCIe core in Quartus 11.0 and am trying to simulate it in modelsim. 6.5 PE I keep getting an error

# INFO: 0 ns Calling req_intf_wait_reset_end# ** Failure: SUCCESS: BFM model not available!

Here's where it stops

 
  app_msi_tc  <= "000" ;
  rp : altpcietb_bfm_rpvar_64b_x8_pipen1b
  port map (
    pclk_in => clk_in,
    ep_clk250_in        => clk250_in,
    coreclk_out        => coreclk_out,    
    npor             => npor,
    crst             => crst,
    srst             => srst,
    -- serdes interface
    rx_in0           => rx_in0,
    tx_out0          => tx_out0,
    rx_in1           => rx_in1,
    tx_out1          => tx_out1,
    rx_in2           => rx_in2,
    tx_out2          => tx_out2,
    rx_in3           => rx_in3,
    tx_out3          => tx_out3,
    rx_in4           => rx_in4,
    tx_out4          => tx_out4,

does anyone know how I can fix this? Thanks!
