ABSTRACT
Electronic design automation (EDA) is a realization of an electronic system or electronic design automation products of technology, with electronic technology, microelectronic technology is closely related to the development, it has absorbed most of the field of computer science and the latest research results, as a high-performance computer Working platform to promote the development of the project. EDA is an important feature of the use of hardware description language (HDL) to complete the design. Super-high-speed hardware description language (VHDL) is the IEEE and the U.S. Department of Defense confirmed the standard hardware description language, since the publication of the IEEE VHDL version of the standard, IEEE-1076, the EDA companies have launched their own VHDL design environment, or to be declared Their design tools and VHDL interface. Since then VHDL gradually replace the original non-standard hardware description language. 1993, IEEE on VHDL was revised from a higher level of abstraction and system capacity expansion VHDL description of the contents. In this paper, based on VHDL language of the elevator control system design, the use of the state machine and a software platform for simulation and experiment. The control system to follow the direction of the principle of giving priority to provide the passenger service users floors and directed the operation of the lift. Note the use of VHDL digital circuit design methods and VHDL in digital circuit design to the important role of simulation, simulation results show that the VHDL language used in digital circuit simulation is practicable, the language in the field of electronic design has been widely accepted.
