How You Can Set Environment Variables
You can set environment variables in these ways:
• Set the environment variable as you would any other environment variable according to your operating system rules.
• Set the environment variable in a special text file called symbol.tbl that resides in the “files” directory of your OpenROAD installation.
During the installation of OpenROAD, the installation process creates a default version of this file that should suffice for most user’s needs.
If you specify an environment variable both in the system environment and in the symbol.tbl file, the system value takes precedence over the symbol.tbl value. This enables you to override the per-installation values specified in the symbol.tbl file (that multiple users would access) by per-user values (especially on multi-user systems such as Windows and UNIX) set in the current user environment.
Some entries in the following lists say “if defined,” which means that you need not assign any particular value to the variable; any value you assign will activate the meaning of the variable. Note, however, that you cannot use an empty value (for example, you cannot specify only “keyword =”). Instead, use a meaningful value such as TRUE.
