Instance is unresolved in module

kirankatamala

Hi,

I am using Altera Quartus 19.1 Standard Edition to generate a testbench system using qsys.

I am using the setup generated by it in to simulate using Xcelium. 

Using shell script , I am getting few following error 

xmelab: *E,CUVMUR (/home/videopath_tb/alt_vip_cl_cvo_191/sim/test_frame_videopath_alt_vip_cl_cvo_191_6d532fy.v,606|10): instance 'test_frame_videopath_tb.test_frame_videopath_inst.interlaced_cvo.cvo_core' of design unit 'alt_vip_cvo_core' is unresolved in 'test_frame_videopath_tb_alt_vip_cl_cvo_191.test_frame_videopath_alt_vip_cl_cvo_191_6d532fy:module'.

Any help in finding solution will be appreciated.

  • This can happen for a number of reasons, for example you might be failing to compile some of the necessary source files (I don't recognise the names so can't tell if those are your modules or Altera ones). Another possibility is that you've used a mixture of 32-bit and 64-bit compilation commands. As we don't have much information to go on from your post, I would strognly recommend you to login to https://support.cadence.com/ and search for the CUVMUR app notes, which contain a lot of good debug information that you can work through.

    Hi StephenH,

    PFA.

    By referring to the above image , looks like cadence folder and related some files are  missing in the Quartus installation directory .

    Please let me know how to generate those missing files in any other way since we do not have any support from Quartus.

    I tried to find the things around, but could not get any help so far.

    I'm sorry, but I have no knowledge of the Quartus software, the fact that the directory is named "cadence" doesn't mean that Cadence has anything to do with delivering the code! I would assume that these files would have been shipped with the Quartus installation or rendered when you configured the IPs in the Quartus software. From the file names I think these must be encrypted RTL / models.

    Another point of note is that the script you've quoted is using the legacy "ncvlog" command instead of "xmvlog" or "xrun" for Xcelium, so I am wondering if you have a very old Quartus that needs to be updated to have proper support for Xcelium?

    Hi StephenH,

    We are using Quartus 191. Standrad Edition for Arria10, which is relatively new. Also we tried xmvlog,xmelab instead of nc commands, issue is same.

    Can you point us where we can generate cadence simulation libraries for Quartus ?

    I think you'll have to ask Intel (Altera) for help with that, the files are owned and delivered by them, not by Cadence.
