We have some very old libraries that need to be added to the Design Architect libraries menu. The ample files were written years ago, around 1992, but they still seem to work. All I have to do is edit the environment variable AMPLE_PATH to source these when Design Architect is started.
Relevant environment variables for adding libraries:
setenv LMC_HOME /net/sw/lmc
setenv AMPLE_PATH
/net/sw/mgc/edg_ample_files:\
/net/sw/libs/edg_lib:\
$LMC_HOME/special/qsim/menus
Here is the old webpage with my notes on what I did with ample files.
