Design a parking lot display system for a closed area parking
consisting of 4 parking
spaces per floor as shown in diagram below. The system will assist
the driver by displaying
total available parking for each floor. You are required to design
and test the system prototype
for a single floor. You can design the system according to your
idea and creativity, but you must use Quartus 9.1
software to write VHDL code to design the system and run the
simulation to prove your system
functionality.
