Trouble with components with multiple src files in QSYS

I was wondering if someone else have seen this problem with the component UI in QSYS. I'm running Quartus II 12.0 with an Arria II GX as target.

I'm trying to make a component using the QSYS component UI. I have several verilog source files that the component includes. I start the component editor and I'm able to setup all the needed things files/signals/interfaces etc. I then save the component and look at the _hw.tcl file. Everything looks good. I can add the component to my QSYS system etc.

The problem comes in when I try to edit the same component. If I look in the files tab I only see the top level file the other files are gone. If I make a change to the component and save it the other source files are removed from the _hw.tcl file and only the top level file is left. It almost looks like the component UI doesn't read the full source file list when it opens.

Thanks

    I have seen this also. So I save the file in the component editor only once, and use the Quartus editor to add/change things later.

    Great at least I'm not the only one. Yeah I went that way as well. I also found that since the component files are copied to a qsys system directory every time you generate the system you can't add .qip files to the _hw.tcl since the files in the .qip file are relative to the qip file location. This can be a big problem if you have megawizard generated cores within the component. I actually now make a .qip file for each custom qsys component and add it to the Quartus project. It atleast work, but it is not pretty.

    BTW I put in an SR for the files issue in the qsys component UI. I might have to add another for the qip issue.

    Here is the response on my service request:

    I tried to check our internal Software Problem Report. There is one qsys component editor issue.

    This issue look very similar to your issue. The issue is that the file is being written out ok, complete with the filesets. However, if you edit the component again, then close without re-adding the files, those filesets will be lost.Only a single file shows up which is top level file in qsys 12.0. The rest submodules files will be gone.

    This issue has been fixed in our internal build 12.0SP2.

    Workaround: Manually add back the missing file as a temporary solution.

    So indeed it is a problem. I'm trying to find out when the SP is due out.

    I got back a response on when this SP will be out and it looks like SP2 for 12.0 will not be released to customers. The fix will be included in release 12.1 instead and that release is not due until November or so.
