ID:330000 Timing-Driven Synthesis is skipped because it could not initialize the timing netlist

CAUSE: You turned on Timing-Driven Synthesis. Timing-Driven Synthesis was not able to initialize the timing netlist, which causes Timing-Driven Synthesis to be skipped. The cause is likely that there is a syntax error in the Synopsys Design Constraints File (.sdc).

ACTION: If you want to run Timing-Driven Synthesis, make sure the Synopsys Design Constraints File is syntactically correct.
