# Hierarchical Flow Blocks
#
# If you are performing a hierarchical flow, define the hierarchical designs here.
# List the reference names of the hierarchical blocks.  Cell instance names will
# be automatically derived from the design names provided.
#
# Note: These designs are expected to be unique. There should not be multiple
#       instantiations of physical hierarchical blocks.
#
#       ICC-ILMs must be included in ${MW_REFERENCE_LIB_DIRS} and require a Milkyway
#       library setup even if you are using DC in WLM (non-topographical) mode.
