Protel 99 SE is a popular software for designing electronic circuit schematics, PCB layouts and simulations. It is used by engineers and hobbyists alike for creating professional and reliable PCBs. If you are looking for a way to download Protel 99 SE for free, you might be disappointed to know that it is not available anymore from the official website. However, there are some alternative ways to get this software on your computer.
Download from Altium Website
The first option is to download Protel 99 SE from the Altium website. Altium is the company that developed Protel 99 SE and later rebranded it as Altium Designer. Altium still provides some older versions of its software for download, including Protel 99 SE. You can find the download link on this page[^1^]. You will need to register an account with Altium and provide some information about yourself and your company. You will also need to agree to the terms and conditions of using the software.
Once you download the installer, you can run it and follow the instructions to install Protel 99 SE on your computer. You will need to enter a license key that will be sent to your email address. The license key will allow you to use Protel 99 SE for a limited time period, usually 30 days. After that, you will need to purchase a license or upgrade to Altium Designer.
Download from Third-Party Websites
The second option is to download Protel 99 SE from third-party websites that offer free software downloads. There are many websites that claim to have Protel 99 SE available for download, such as Get Into PC[^2^]. However, you should be very careful when using these websites, as they may contain viruses, malware, spyware or other harmful programs that can damage your computer or steal your personal information. You should also check the legality of downloading Protel 99 SE from these sources, as it may violate the copyright or license agreement of Altium.
If you decide to download Protel 99 SE from a third-party website, you should scan the file with an antivirus program before opening it. You should also make sure that the file size and name match the original Protel 99 SE installer. You may need to use a crack or patch to bypass the license verification process, which can also pose a security risk or cause errors in the software.
Protel 99 SE is a powerful and versatile software for PCB design that can help you create high-quality and functional PCBs. However, it is not easy to find a legitimate and safe way to download it for free. The best option is to download it from the Altium website and use it for a trial period, or upgrade to Altium Designer which offers more features and support. Alternatively, you can try downloading it from third-party websites at your own risk, but be aware of the potential dangers and legal issues involved.
Protel 99 SE Features
Protel 99 SE offers a range of features that make PCB design easier and faster. Some of the main features are:
Design Explorer: A unified environment that integrates all the tools and processes for schematic capture, PCB layout, simulation and output generation.
Schematic Editor: A graphical editor that allows you to create and edit circuit diagrams with ease. You can use libraries of components, symbols and models, or create your own. You can also run simulations and verify your design with electrical rules checking.
PCB Editor: A powerful editor that enables you to design and edit PCBs with precision and flexibility. You can use advanced routing and placement tools, design rules checking, copper pouring, 3D viewing and more. You can also import and export data from other CAD tools.
Simulation: A feature that allows you to test and analyze your circuit performance using SPICE-based simulation engines. You can run various types of simulations, such as DC, AC, transient, noise, parametric and more. You can also view the results in graphical or tabular formats.
Output Generators: A feature that allows you to generate various types of outputs for your PCB design, such as Gerber files, drill files, netlists, reports and more. You can also customize the output settings and formats according to your needs.
Altium Designer Features
Altium Designer is the successor of Protel 99 SE and the current flagship product of Altium. It is a comprehensive software for PCB design that offers more features and capabilities than Protel 99 SE. Some of the main features are:
Unified Design Environment: A single environment that integrates all the aspects of PCB design, from concept to manufacturing. You can access all the tools and data you need from one place.
Modern User Interface: A user-friendly interface that is easy to learn and use. You can customize the workspace, toolbars, menus and shortcuts according to your preferences.
64-bit Architecture: A software that can handle large and complex designs with ease. You can work with multiple boards, layers, components and nets without compromising performance or stability.
Cloud Collaboration: A feature that allows you to collaborate with other designers online. You can share your projects, files and comments in real time using Altium 365 platform.
ActiveRoute: A feature that allows you to route your PCBs automatically with high quality and efficiency. You can use intelligent algorithms, interactive guidance and user-defined rules to achieve optimal routing results.
Multi-board Design: A feature that allows you to design multiple PCBs as part of a single system. You can define the connections between the boards, synchronize the changes and generate outputs for the whole system.
