Let's take SMV as an example. To add the path of some binary files to the Mac system, there are multiple ways.

Someone may want to modify /etc/profiles, however it is suggested that modifications to the above files may result in serious system problems. Instead,make changes in your personal home directory, e.g., ~/.profile.

cd ~/.profile;

add the following information accordingly, e.g. for Cadence SMV,

export PATH=$PATH:/Projects/smv/bin
export MANPATH=$MANPATH:/Projects/smv/man
export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:/Projects/smv/lib

Note that for the last statement, LD_LIBRARY_PATH will be used on Linux.

These changes will not take effect immediately, so do the following to reflect the changes (to reload the file):

source ~/.profile

Now type the command to see if it's system wide available.
