Xilinx uses the industry standard IP-XACT format for delivery of IP, and provides tools (IP packager) to package custom IP. Accordingly, you can also add your own customized IP to the catalog and create IP repositories that can be shared in a team or across a company. IP from third-party providers can also be added to this catalog, provided it is packaged in IP packager, even if it is already in the IP-XACT format.
