file, and have the following format:
setenv <environment variable> <value>
If you are using the Bourne or Korn shell, environment variables are located
in your .profile file, and have the following format:
set <environment variable> = <value>
Quartus II General Environment
Variables
The Quartus II software installation process initializes the following
variables, but you may wish to change them to optimize your system
performance.
QUARTUS_ROOTDIR
The QUARTUS_ROOTDIR variable specifies the name of the Quartus II
system directory. The default directory is /opt/altera<version number>. You
should change this variable only if the system displays an error message
indicating that Quartus II files cannot be found when you start the program.
