Field programmable gate arrays (FPGA) is a new programmable logic devices, has a higher density, faster pace of work and greater programming flexibility, is widely used in various electronic products . The hardware description language (HDL) is a fast circuit design tools, its functions cover the circuit description, circuit synthesis, circuit emulation, such as the three circuit design. VHDL HDL is a kind, because of their easy-to-understand and widely used. In this paper, VHDL programming of the adder design, for the adder to provide the hardware to achieve the draw. With the rapid development of EDA technology, electronic system design techniques and tools profound changes have taken place, large-scale programmable logic device CPLD / FPGA the emergence of designers to bring a lot of convenience. Use it for product development, not only low-cost, short-cycle, high reliability and with full intellectual property rights
