Hardware Description Language (Hdl): An Efficient Approach to Device Independent Designs for Vlsi Market Segments

By Dr.kennedy Chinedu Okafor


Contemporarily, owing to astronomical
advancements in the very large scale integration (VLSI)
market segments, hardware engineers are now focusing on
how to develop their new digital system designs in
programmable languages like very high speed integrated
circuit hardware description language, (VHDL) and Verilog
and consequently target it to Complex programmable logic
devices (CPLDs) and Field programmable gate arrays
(FPGAs). This paper focuses on using VHDL, to design an
application specific integrated circuit (ASIC) liquid
dispenser controller system while targeting the device
independent architecture (Ultra 3700 CPLD series) for
synthesis ,optimization and fitting to realize the design. The
ASIC controller has two bin cans to dispense regular and diet
drinks. The system dispenses a drink if the user activates a
button for that drink and at least one can is available. A refill
signal appears when both bins are empty. Activating a reset
signal informs the system that the machine has been refilled
and the bins are full. The design methodology is presented
with other details in the body of this paper.
