The Design Architect-IC tree from Mentor Graphics cannot be installed in our current MGC tree, so I put it in its own directory: /net/sw/mgc/icflow2007_2a. However, it does require that MGC_HOME be set to /net/sw/mgc/icflow2007_2a/2007.2a_rhelx86linux/icflow_home. This is a problem, since MGC_HOME also must be set to our current MGC tree. So, since this program will definitely not be used as much as the regular MGC tree, I created an alias in /etc/profile.d/da-ic.csh that has the following:
alias setup_da_ic "setenv MGC_HOME /net/sw/mgc/icflow2007_2a/2007.2a_rhelx86linux/icflow_home"
Whenever a user would like to use the da_ic program, he should open a new window and run:
setup_da_ic
which will change the MGC_HOME environment variable. Then, the program can be started by running da_ic. The path does not need to be changed because it’s always set to find the da_ic program.
