How to rectify modelsim error "missing ALT2GXB.v"?

I was trying to simulate PCI Express reference design as per instructions given in "IP compiler for PCI Express" document. Reference design file I downloaded from altera website and copied in the system. When runtb.do file is runned an error message missing "ALT2GXB.v" is shown in the screen.

I tried to download this file. But I am not getting any source. Help please.

    Probably some screenshot or Modelsim error message will be helpful. Also, you might want to share the link of the reference design for clarity.

    ALT2GXB.v file was available in quartus library. I copied that file pasted in respective folder. Now modelsim is not throughing any error.

    Glad to hear that you have found the workaround. It seems like this ALT2GXB.v file is missing from the reference design that you have downloaded?

    By the way, mind sharing the reference design link which seems to have missing file?
