**Introduction to Protel**
Protel is an EDA (Electronic Design Automation) software developed by Altium in the late 1980s. It has long been a leading tool in the electronics design industry and is widely recognized for its comprehensive features and reliability. In China, it was one of the first EDA tools introduced and remains the most popular among electronic engineers. Many universities offer courses on Protel, and it is commonly used in both small and large electronics companies. When hiring electronic design professionals, many firms specifically mention Protel as a required skill.
Originally, Protel was mainly used as a PCB (Printed Circuit Board) automatic routing tool that ran in a DOS environment. It had very low system requirements and could operate on a 286 computer with just 1MB of memory, without needing a hard disk. However, at that time, it only offered basic functions such as schematic capture and simple PCB layout. The automatic routing capabilities were limited compared to modern standards.
Today, Protel has evolved significantly and is now known as DXP 2004. This version is a powerful, full-featured EDA suite designed for Windows 95 environments. It offers a complete board-level electronic design system, including circuit schematic design, simulation of analog and digital circuits, multi-layer PCB design, programmable logic device design, report generation, spreadsheet integration, and macro support. It also supports a client/server architecture and can import files from other design tools like ORCAD, PSPICE, and Excel. Its advanced multi-layer PCB automatic routing ensures a 100% routing success rate for high-density boards.
Protel is easily accessible in China, with numerous books, tutorials, and online resources available for users. You can also download a trial version of Protel99 from the internet to explore its features. Its popularity continues to grow due to its user-friendly interface and extensive functionality.
