FPGA technology is used to make logic systems and it is majorly based on Computer-Aided Design (CAD). In this paper, the main aim is to introduce and implement our own logic for high security optical shaft encoder for an artificial limb using Xilinx software on FPGA. FPGA is used to design prototype hardware before final implementation. This will reduce cost as well as time. Now a day, Security is the most important issue for rucks. Therefore, to reduce their problems of security we implement high security optical shaft encoder for an artificial limb by providing security login system using finite state machine.

Keywords: VHDL (Very High Integrated circuits Hardware Description Language), FSM (Finite State Machine), OSE (Optical Shaft Encoder), FPGA (Field Programmable Gate array), Xilinx14.2
