Jul 10, 2007Hi , I assume cell type means , ref name of the flop. Is it correct?. If so, below command will tell you which flop is mapped  question on design compiler | Forum for ElectronicsDatabase commands in IC compiler - Forum for ElectronicsSynopsys IC compiler : using regular expression in IC commands[SOLVED] - replacing lvt cells with rvt cells - Forum for ElectronicsMore results from www.edaboard.com

How does design compiler read setup files?

Design Compiler reads the setup files from three directories in the following order:

  • 1.
    The Synopsys root directory ($SYNOPSYS/admin/setup) This system-wide setup file cont ains system variables define d by Synopsys and general Design Compiler setup information for all users at your site.
    Only the system administrator can modify this file. 2.

    • How does design compiler write out a DEF file?

    Design Compiler writes out the file using DEF syntax version 5.7 only.
    If you reuse the DEF output, you must read it in from the top level of the design with the extract_physical_constraintscommand.
    The following example uses the write_defcommand to write the placement information to a DEF file:.

    What happens if design compiler does not find a reference?

    Design Compiler uses the first reference it locate s.
    If it locates additional references with the same name, it generates a warning message identifying the ignored, duplicate references.
    If Design Compiler does not find the reference, a warning appears advising that the reference cannot be resolved.
