# Need to FLATTENING the design before OCP and NERO
# Use x2y vst vst <source> <result>
# then flatlo -r <source> <result> # source is a result from x2y
# this two sequence will remove most warning/error message when
# performing LOON on the netlist.
#
# BOOM will optimize the logic
# BOOG will optimize/convert the logic into netlist
# LOON will optimize the netlist (this will report area/timing)
#
# VST is a circuit netlist file
# AP  is a circuit placement file (OCP/NERO create this file)
# VBE is alliance VHDL Behavioral Description file
