In project mode, the tool automatically reads in the last DCP file from when synthesis was the last run if running in default mode or any DCP that is specifically mentioned. In non-project mode, the reference DCP must be read before synthesis. The command for that is:
read_checkpoint -auto_incremental -incremental<path to dcp file>Or
read_checkpoint -incremental <path to dcp file>After this, run the synth_design command as normal.
Note: The
-auto_incremental
option in read_checkpoint is the same as the default
behavior in the IDE.
