    SDC Syntax
    vU-2003.03 Using the Synopsys Design Constraints Format Application Note A SDC Syntax A The following tables list the commands and arguments supported by SDC version 1.4. The arguments listed in the unsupported arguments column are supported by Design Compiler or PrimeTime, but are not valid in the SDC format. For more information about these commands, see the man pages in either Design Compiler or PrimeTime.
