3.3. Exporting and Importing Safety Logic Partitions

When exporting safety logic containing several partitions, because each partition is standalone, export each as a separate database .qdb file.
  1. Export after the Fitter (Finalize) stage in the design creation flow.
  2. Export .qdb file in GUI from the context menu of partition.
    Alternatively, export .qdb using command line, use the equivalent Tcl command in the Quartus® Prime Pro Edition software.
    Figure 29. Export .qdb file for the Safety Logic Partition in Design Creation Flow
    Figure 30. Export .qdb file for the Safety Partition in Design Creation Flow
  3. Subsequently in the design modification flow, import the safety logic partition .qdb files.
  4. To import .qdb file, specify the Partition Database File field in the GUI.
