Initialization

In order to use Design Compiler, you must set up your environment correctly. This includes setting up a few variables, files, and licensing information and can be done by sourcing the scripts shown below.


Linux

First, check this link to find out the available versions of synthesis tools currently installed on Linux machines. Then, initialize the tool by running the respective source script. You should always select the latest version available unless you have a reason to use an older version.

$ source /share/tktprog/synopsys/syn-2007.03-SP2/syn.sh

Solaris

First, check this link (mustatikli) to find out the available versions of synthesis tools currently installed on Solaris machine. Then, initialize the tool by running the respective source script. On Solaris platform you may use either 32-bit or 64-bit binaries. You should always select the latest version available unless you have a reason to use an older version.

$ source /opt/synopsys/syn-2007.03-SP2/syn32.sh

After sourcing the given script you should see a message similar to the one below (the actual message may differ depending on the tool version and platform) indicating that the source script was read and your environment set up correctly:
