Synopsys DC installation

4.Uncompress and untar the Synopsys Installer file in a separate installer directory.
         % mkdir -p /usr/synopsys/synopsysinstaller 
         % mv synopsysinstaller_v1.0.<n>.tar.Z /usr/synopsys/synopsysinstaller 
         % cd /usr/synopsys/synopsysinstaller 
         % cat synopsysinstaller_v1.0.<n>.tar.Z | uncompress | tar xvf -

  5. Add the installer directory to your UNIX path.
        
         % set path=(/usr/synopsys/synopsysinstaller $path)    

   6. To install the software, enter one of the following installation commands:

         % ./install.now (to use text prompts)

         % ./setup.sh (to use the GUI)

Setting Up the User Environment
========================================================

 To set up your users, you must create a Synopsys source file, or modify 
 each user's $HOME setup files (typically .cshrc, .profile, .kshrc, or .bashrc), 
 as follows. For tool-specific information, see "Setting Up <product_name> 
 for Each User" in the appropriate tool chapter in the Installation Guide.


    1. Set SNPSLMD_LICENSE_FILE, LM_LICENSE_FILE or a tool-specific licensing variable.
  
       This variable specifies the path to the Synopsys FLEXlm license server.

       Note:
         SNPSLMD_LICENSE_FILE is supported only for tools using the snpslmd Synopsys 
         Common Licensing (SCL) daemon. LM_LICENSE_FILE is supported for all Synopsys 
         tools (all daemons).

       In the following example, it is assumed that the Synopsys license server 
       is using TCP port 27000, the default port. (However, you can specify another
       port by modifying the SERVER line of your site's keyfile--for example, 
       "SERVER myserver 8308a297 26585.")
     
       Example:

         * Add to .cshrc
           
            setenv SNPSLMD_LICENSE_FILE 27000@myserver  
            or
            setenv LM_LICENSE_FILE 27000@myserver 
      
          * Add to .profile, .kshrc, or .bashrc
         
            SNPSLMD_LICENSE_FILE=27000@myserver; export SNPSLMD_LICENSE_FILE  
            or
            LM_LICENSE_FILE=27000@myserver; export LM_LICENSE_FILE

  
    2. Add the tool executable files to the user path.
    
       Example:

         * Add to .cshrc:

           set path=(synopsys_root/<platform>/<product>/bin $path)

         * Add to .profile, .kshrc, or .bashrc:

           PATH=synopsys_root/<platform>/<product>/bin:$PATH
           export PATH

       Note:
         For some tools, the appropriate directory of executable files
         is synopsys_root/bin.


    3. Set any tool-specific variables.

       In many cases, tool-specific environment variables must be set. 
       Typically, you need to set an environment variable that points 
       to the root directory for the Synopsys tool.

       Example:

         setenv SYNOPSYS /path/to/synopsys_root

       Note:
         Not all tools use the $SYNOPSYS environment variable. In some
         cases, other tool-specific variables must be set.  See the 
         Installation Guide for details.
