AbstractElectronic circuit design is the backbone of modern information technology, science, is engaged in the design of various ponents, circuit design and electronic system design and manufacture of highly technical subjects, but also our human resources is urgently needed to develop and field of expertise. Engineers in the industry with electronic circuit design applied to the basic theory, basic knowledge and basic skills, with electronic technology, electronic information system modeling, electronic circuit design, electronic design automation tools and hardware description language applications, microelectronics and semiconductor manufacturing processes, integrated circuit design and electronic design automation and other aspects of prehensive ability and engineering practice.For now a lot of PCB design software, such as Protel 99se, Altium39。s 2004 version, Power PCB , there is Power and Power Logie bination version (PADS PCB), which is now the latest version of PADS Software, domestic very few engineers in this area.Protel DXP 2004 incorporates the world39。s leading EDA features and technology, its main function integrated schematic design, PCB design, Spice simulation, VHDL simulation and synthesis, signal integrity analysis and CAM file editing and verification. To a certain extent, Protel DXP 2004 design tools to break the traditional pattern, provides projectcentric design environment, including the powerful navigation capability, source code control, object management, design variables and multichannel design, advanced design methods. In this great work in the CAD, the use of Protel DXP 2004, drawing 10M Ethernet munication ARMbased PCB design system.Keywords: Protel DXP 2004, package, PCB plans5. 附錄PCB原理圖
