sopcinfo-file: afte Qsys generation -> info of subcompents is missing

[Altera_Forum]

Hi community, 

 currently I am working with the Quartus II 12.1 Sp1 and I have to restructure my design to simplify the version control of the subcomponents and to be able to configure my system more generic.  The idea was to export some qsys subcomponents as _hw.tcl files, as the qsys file format is XML based and changes a lot of the content every time a single change is made in the QSYS.  I have exported the subcomponents by opening the qsys-files and export them in QSYS.  After this I had to make a view changes in the tcl-files, such as the NAME, DISPLAY_NAME and DESCRIPTION. This has to be done as I want to replace the qsys-components with the corresponding _hw.tcl-components in the "component library" of QSYS. Next I have deleted these qsys files. Then I have moved the _hw.tcl-files separated in new folders of the same title(name of the components). Next I have moved these folders in another directory and had to adapt the .ipx-file.  Then I rerun QSYS and was satisfied as I could not notice any changes in the design.  The problem appeared after successfully generating the system.  The sopcinfo-file has been changed dramatically, as the information of the former subcomponents, which has been exported, is missing (recognized with tortoise->diff).   why is there a difference in the sopcinfo-file, when generating a system with mixed (qsys-files and _hw.tcl-files) subcomponents???:confused:  i hope someone can help me, as i found no documentation about QSYS and its generation of the sopcinfo-files!  Thank you a lot and kind regards

Hi again, 

 The problem seems to be solved! I have reported this problem to the Altera customer support and got a solution. The solution is to add following commandt to the *_hw.tcl-subcomponent's# default module properties": "set_module_property opaque_address_map false".  After regeneration the *sopcinfo-file includes all necessary information. I hope that this statement will be added automatically in the future versions of QSYS.  Many thanks to Altera's friendly support team, they really have made a great job.  Bye
