Error (12002): Port "din" does not exist in macrofunction "ior" File: - Error (12002): Port "din" does not exist in macrofunction "ior" File: Description When you compile an example design of 40- and 100-Gbps Ethernet MAC and PHY MegaCore® function, the following error message might be reported. Error (12002): Port "din" does not exist in macrofunction "ior" File: [path]/alt_e100_top_sv.v Line: 164 This is because you generated the IP with Avalon®-ST Interface but compiled an example design with Custom Streaming Interface. Resolution Compile a proper example design for your IP variation. Even if you generated the IP with Avalon-ST Interface, the MegaCore function generates example designs for all variations, including the Custom Streaming Interface version.
