The Vivado core update functionality can be used to import an existing XCO file from v5.0 and upgrade to FIR Compiler v7.2, but it should be noted that the update mechanism alone does not create a core compatible with v5.0. See Instructions for Minimum Change Migration. FIR Compiler v7.2 has additional AXI4-Stream parameters. The following table shows the changes in parameters from v5.0 to v7.2.
