## Overview

This repository appears to be an FPGA vending-machine project implemented in VHDL and opened as a Quartus project. The reference-file names indicate customer vending and payment scenarios, plus technician setup and price changes. The likely user-to-result workflow is selecting an item, paying, and vending it, with technician configuration as a separate capability. No source excerpts were provided, so module responsibilities and call relationships cannot be verified; the graph therefore shows the VHDL modules without inferred connections.
