1. Make sure your server has Solaris 9 (or later) loaded. 2. Make sure your server has at least 4 GB of memory (physical and swap space) available. Note: Physical memory equals data size plus stack size, but stack size is used before data size. Therefore, setting stack size to a large value causes problems for designs that need to go over 2 GB. If you set the stack size too high, you cannot get enough memory for your data. To check the settings, use the limit command at the system prompt. For more information, see Installing Synopsys Tools. 3. Make sure the system you are using does not have restrictions that prevent you from using more than 2 GB of memory. 4. Create unlimited data size in the shell that you are using: C, Bourne, Korn, or Bash. If there are system-wide limits on the data size you can create, you can remove them or override them. You can do this in one of two ways: • Enter one of the following commands: For the C shell, % limit datasize 3800000 For the Bourne, Korn, or Bash shell, # ulimit -S -d 3800000 • Modify the kernel of your server. This approach allows everyone using your server to extend memory beyond 2 GB.
