DCT流程具体如何操作

5.Ensure that you have all the necessary design-specific input files to be used
in the flow.These files are picked up automatically from the search path
defined in common_setup.tcl
The minimum recommended files are
o${DCRM_CONSTRAINTS_INPUT_FILE} (Logical design constraints)
o${DCRM_DCT_DEF_INPUT_FILE} or ${DCRM_DCT_FLOORPLAN_INPUT_FILE}
(floorplan to use for topographical mode synthesis)
o${DCRM_DFT_SIGNAL_SETUP_INPUT_FILE} (DFT signal definitions)
For a complete list of expected input files, see the list at the end
of this README file.

从图上来看，我是要先使用dc进行综合，这里dc会粗略地布一下局，然后综合出结果。然后我用dc综合出来的结果进行icc综合。icc综合后会有一份def文件，我再把这份def文件当作dc的输入，再进行一次icc综合?
