Error! Unknown INTENDED_DEVICE_FAMILY=Stratix IV during Arria 10 PCIe hip simulation

I have generated an Arria 10 PCI Express testbench system using Platform Designer in ACDS 24.3. When I come to simulate this system using the generated msim_setup.tcl script, I see this sort of mess...

    Hi gavin5342,


    My apologies for the late reply.

    Thank you for attaching the .ip file.


    I have generated the simulation files from the .ip file given and run the simulation in Questa Intel FPGA Edition-64 2024.1. I can replicate the error messages that you observed.


    Based on my findings, there are 7 instances that returned the comment of "# Error! Unknown INTENDED_DEVICE_FAMILY=Stratix IV.". This is reported because the INTENDED_DEVICE_FAMILY parameter was defined as Stratix IV, but it is not found in the IS_VALID_FAMILY function's list of device families.


    So, when the code performs a check on this function using the parameter INTENDED_DEVICE_FAMILY for the 7 instances, the error message is reported. I think our IP design team will reuse some proven RTL for the next generation of devices. Hence, your observation is expected.


    Additionally, with the message "# SUCCESS: Simulation stopped due to successful completion!", this indicates a successful simulation. Therefore, I think you can safely ignore the error comment.


    I hope this addresses your question. Please let me know if you have any further inquiries.


    Thanks.

    Best Regards,

    ventt

Sorry for the delay Ven. Yes, I agree that I can safely ignore the message, it's just annoying that the auto-generated files put me into the situation where I need to ignore spurious errors.

A couple of ways you could make things easier for the future:

1) Update the PCIe tbed so that it doesn't specify Stratix IV any longer

2) Update altera_mf.v so that it accepts Stratix IV even though Stratix IV is not supported by Quartus Pro

Thanks for your help,
Gavin

    Hi @gavin5342 ,

    Thanks for your reply and the feedback.
    I agree with you that the warning message can be annoying, even though we know it causes no harm.

    I will provide your feedback to the internal team.
    Kindly note that the ultimate decision to implement the changes lies with the internal team.

    We appreciate your feedback. Have a good day!

    Thanks.
    Best Regards,
    Ven Ting
