The reference design is usually an earlier iteration or variation of the current design that has been synthesized, placed, and routed. However, you can use a checkpoint that has any amount of placement, routing, or both. The reference design checkpoint (DCP) might be the product of many design iterations involving code changes, floorplanning, and revised constraints necessary to close timing. After the current design is loaded, load the reference design checkpoint using the read_checkpoint -incremental <dcp> command. Loading the reference design checkpoint with the -incremental option enables the Incremental Compile design flow for subsequent place and route operations.
