General Description: If a PIM contains more than one NGO (that is, the module netlist instantiates another, non-module netlist), NGDBUILD does not find the lower-level NGO file when run in assemble mode. It finds the top-level NGO of the PIM okay, but not the lower-level one in the same directory.
This problem can be worked around by a adding an explicit search path "-sd <path_to_pim_directory>" to the NGDBUILD command line. If a search directory is already in use, the NGOs could be moved into that directory.
This problem will be fixed in the first 3.1i quarterly release, currently scheduled for August, 2000.
