How to create Separate System in Qsys Under IP Catalog ?

--- Quote Start ---

As long as Qsys (now called Platform Designer) can "see" a .qsys file, it gets listed in the IP catalog. For it to see the file, it needs to be in the same directory as the current .qsys, in a directory named ip one level down from the current .qsys file, or in a custom location specified in the tool's options.
