# Be aware of required VHDL_ENTITIES sequence! All entities must be listed in
# bottom to up order (e.g. the top entity is the last in this list). Otherwise
# it won't compile.

# Target 'view' can be used to compile & run testbench and show the result
# in gtkwave. When lauching gtkwave, timing diagram settings (named after
# the testbench) is also loaded, so it's possible to store view settings
# by invoking 'File/Write Save File (Ctrl+S)' in gtkwave.
