<h2 History of Protel PCB Design Software
Protel PCB design software has a long and rich history that spans over three decades. It started as a simple and affordable tool for hobbyists and enthusiasts, and evolved into a sophisticated and professional tool for engineers and designers.
From Protel to Altium Designer
The story of Protel begins in 1985, when an Australian company called Protel Technology Pty Ltd was founded by Nick Martin, a former electronics engineer and computer programmer. He developed the first version of Protel PCB design software, called Protel PCB, for the MS-DOS operating system. It was one of the first PCB design tools that could run on personal computers, and it offered features such as schematic capture, PCB layout, autorouting, and Gerber file generation.
Protel PCB was well received by the market, and soon became popular among hobbyists and small businesses who wanted an affordable and easy-to-use PCB design tool. Protel Technology continued to improve and expand its product line, releasing new versions of Protel PCB with more features and capabilities, such as mixed-signal simulation, 3D visualization, and database management.
In 1998, Protel Technology changed its name to Altium Limited, reflecting its ambition to become a global leader in electronic design automation (EDA) software. It also launched a new version of Protel PCB design software, called Protel 98, which was a major overhaul of the previous versions. It had a new user interface, a new file format, and a new integrated design environment that combined schematic capture, PCB layout, simulation, documentation, and collaboration tools in one platform.
Since then, Altium has continued to develop and enhance its flagship product, renaming it as Altium Designer in 2005. Altium Designer is now one of the most widely used and respected PCB design tools in the industry, offering features such as advanced routing technologies, high-speed design capabilities, cloud-based collaboration tools, and support for emerging technologies such as rigid-flex boards, embedded systems, and Internet of Things (IoT) devices.
