Vending Machine as we all know is a machine which can vend different products which is more like an automated process with no requirement of man handling which we normally see in fast moving cities because of fast paced life. This paper compares different aspects like area, timing constraint, speed, power dissipation of a vending machine with 2 different design styles algorithm while installation. FSM based algorithm has been utilized to simulate model, synthesize the machine on the stratix III family of FPGA provided with quartus design tool which is logic device design software from Altera. © 2014 IEEE.
