HDL implementation of prepaid electricity billing machine on FPGA

This Paper presents a novel implementation of a prepaid electricity billing machine (PEBM) on Xilinx Spartan6 FPGA device XC6SLX16 package 3csg324. An interactive interface has been designed to make user interaction with the system at runtime. Power analysis of the system is done with Xpower Analyzer tool which shows a total power consumption of 0.034W. Maximum frequency on which this system can work efficiently is estimated at 143.798 MHz. This machine is developed keeping in view its use in residential areas, institution, corporate companies and big organizations, and the demand for fully automated systems.
