Differences between Qsys and IP Catalog

The main reason for the difference in setting IP in Qsys and IP Catalog is due to their distinct purposes. Qsys is designed for system-level integration, where you connect various IP blocks and create a complete system, while the IP Catalog is focused on configuring individual IP blocks before they are integrated into a design. The differences in their interfaces and functionalities reflect these distinct roles. That is the reason you see difference interface for no Avalon-MM & Avalon-MＭ with DMA options In the IP Catalog.
