Hard PCIe simulation with Avalon-ST interface always fails in ModelSim?

I've been trying to run the runtb.do script created when instantiating a PCIe hard block with the MegaWizard. It always fails with incorrect number of ports in the generated modules. Has anyone successfully simulated this config?

I've tried PCIe gen1 x1, and a PCIe gen2 x8, and they both fail the same way. Tools are QII 9.1sp1 and ModelSim-AE 6.5b. I would expect the instance to run without issue; nothing was touched. Did Altera maybe update the core or testbench, but not both??

Here's the ModelSim transcript output:

    Have you installed the service pack for Modelsim 6.5b for Quartus II 9.1 that is shown on Altera's website? I seem to remember running into a similar port mismatch issue that was resolved when I installed the service pack for modelsim.

    I can't say for sure that this is the exact issue, but it smells very similar to what I ran into...

    Peter,

    Here is how I found the patch:

    (1) go to altera.com

    (2) hover over "Products" and select "Design Software" from the dropdown

    (3) click on the "Quartus II Subscription Edition Software" link

    (4) click on the "Download Software" link under "Next Steps"

    (5) select the "Download Service Pack" link under the "Download" button for Modelsim-Altera Starter Edition v6.5b for Quartus II v9.1

    I hope this helps.

    That fixed it! Thanks for the pointer!

    It's weird that my ModelSim is still 6.5b - I guess there's no indication of which service pack is being used.

    Peter,

    Glad that it fixed it...I agree, it would be nice if there was an indicator stating that the service pack was installed or not. Actually, now that I think about it, the update is probably a library update, not an update to the modelsim code...

    Ya that would make more sense. It's a big update though - 600 MB. I was thrown off by the fact that the ports really are mismatched in the RTL, making me think Altera was generating the wrong code. Anyways I'm glad I can do sims now!
