Webfor my clock tree synthesis, I use the ccopt flow, and I source the following commands: setCTSMode -engine ccopt. create_ccopt_clock_tree_spec -file ccopt.spec. The .spec file should be based on my .sdc. However, in the generated .spec file I can read something like the following: # Clock tree offset inferred from set_clock_latency -source ... WebThe clock tree specification contains clock_tree, skew_group, and property settings. Alternatively, the specification can be written to a file for inspection or debugging purposes and then loaded. create_ccopt_clock_tree_spec #create_ccopt_clock_tree_spec –filename ccopt.spec #source ccopt.spec.
