How to add top level generic into a Qsys system?

Some custom VHDL components in my Qsys system have test modes. These are controlled via generics on their top level. These components are currently in a Qsys system. In Qsys, I can click on them and ...

Hi,

Thanks lot for your clarification. As I understand it, you would like Qsys to be able to allow setting/exporting of subcomponent generics up to the qsys_system level. This is so that when you instantiate the qsys_system as a submodule to another top level, you are able to pass the generics from top level to qsys_system and down to the Qsys sub component.

If my understanding is correct, as I discussed with my peers, it seems like currently this is something not supported by Qsys. As a workaround, you might need to manually edit the qsys_system.vhd file to export the generics. Sorry for the inconvenience. I will look into filing enhancement on this for future software release.

Please let me know if there is any concern. Thank you.

Best regards,

Chee Pin

    Dear cpchan, Yes, you understood the problem correctly. Its just that when manually editing Qsys files, the changes are lost when we regenerate the system. Regards, Hassan Iqbal
