**Introduction to Protel**
Protel is an EDA (Electronic Design Automation) software developed by Altium in the late 1980s. It has long been recognized as one of the leading tools in the electronics design industry, and it remains a top choice for electronic engineers worldwide. Protel was introduced to China earlier than many other similar software solutions, and it quickly gained popularity due to its ease of use and comprehensive features. As a result, it has the highest penetration rate in the country, with many universities offering courses on Protel and most electronics companies relying on it for their design processes. Many large corporations even specify that candidates should have experience with Protel during the hiring process.
Originally, Protel was primarily used as a printed circuit board (PCB) automatic routing tool, running in a DOS environment with minimal hardware requirements. It could operate on a 286 machine with just 1MB of memory and no hard drive, though its functionality was limited to basic schematic capture and PCB layout. Over time, Protel evolved significantly, with the latest version being DXP 2004. This modern version is a full-featured EDA system designed for Windows 95, featuring advanced capabilities such as schematic design, analog and digital mixed-signal simulation, multi-layer PCB design, programmable logic device design, and more. The full installation can exceed 200MB, reflecting its extensive feature set and robust performance.
Protel offers a wide range of functions, including schematic drawing, simulation of both analog and digital circuits, PCB layout with high-density automatic routing, and support for various file formats like ORCAD, PSPICE, and Excel. Its client/server architecture makes it suitable for team-based projects, and its user-friendly interface helps streamline the design process. In China, Protel is widely available, and there are numerous books and online resources to help users learn and master the software. You can also find trial versions of Protel99 online if you're interested in exploring its features firsthand.
