AbstractThe Abstract The E1ectronic Design Automation(EDA)technology has become an important design method of analog and digital circuit system as the integrated circuit’8 growing．The EDA technology，which is closely connected with the electronic technology，microelectronics technology and computer science，can be used in designing electronic product automatically．It was firstly put forwarded In 70s。And till now there has been three stages of the EDA．That is the computer aided design(CAD)of electronic circuit in 70s,the computer aided engineering (CAE)in 80s and the electronic system design automation(ESDA)in 90s．The ESDA， Which is called EDA nOW，is based On the automatic synthesizer and the hardware description language(HDL)．The design result of EDA Can not only be verified by FPGA／CPLD but also be implemented through the Application Specific Integrated Circuit(ASlC)．One important characteristic of the EDA is that the design documents should be completed by the HDL．The VHDL is one of the standard hardware description languages validated by IEEE， which was firmly introduced in 1982．And it was widely used by electronic designer now． We firstly present some background information of EDA，PLD devices in {his thesis．The principle and analyze of Intel805 1 then was introduced．and then introduced the information about the FPGA／CPLD，VHDL language and the software MAXPLUS，also the design plan is introduced．The design of a digital 8051 system，which is fulfilled by the VHDL，is also be discussed．Finally the cUrrent development trend of the EDA and my several experiences about the designing ofthe system are related． The key point in this paper is the method how to design the CPU and the DAC．It’S mainly focus on the realization ofALU，the method to design the Finite -Ⅱ· State State Machine in tlle contr01 unit and the realization of the∑．A modulation arithmetic with VHDL．Through the design and realization of the arithmetic above， we can know the VHDL have lots of advantage and char
