If you are looking for a powerful and easy-to-use auto-router for your printed circuit board (PCB) design, you might want to consider downloading Specctra Router. Specctra Router is a standard interface that works with many CAD tools, such as KiCad, Eagle, LayoutEditor and more. It can import DSN files generated by these tools and export SES files that contain the routed board. In this article, we will show you how to download Specctra Router and use it for your PCB design.
What is Specctra Router
Specctra Router is a software that can automatically route traces on your PCB layout, according to your design rules and constraints. It can handle complex designs with multiple layers, SMD devices, blind and buried vias, and different routing modes. It can also optimize the routing quality and performance by minimizing crosstalk, noise, length mismatch and other issues.
Specctra Router was originally developed by Cooper & Chyan Technology in the 1980s and later acquired by Cadence Design Systems. It is now available as a standalone application or as an integrated module in some CAD tools. It is widely used by PCB designers around the world for its speed, accuracy and flexibility.
How to Download Specctra Router
There are two ways to download Specctra Router: either as a standalone application or as a plugin for your CAD tool.
Download Specctra Router as a standalone application
If you want to download Specctra Router as a standalone application, you can visit the GitHub page of freerouting/freerouting[^1^]. This is an open source project that maintains and updates the original Specctra Router code under the GPL license. You can find the latest release of freerouting.jar file on the Releases page[^2^]. You can run this file on any platform that supports Java.
Download Specctra Router as a plugin for your CAD tool
If you want to download Specctra Router as a plugin for your CAD tool, you need to check if your tool supports the Specctra or Electra DSN interface. Some of the popular CAD tools that support this interface are KiCad[^3^], Eagle, LayoutEditor and Proteus. You can find the instructions on how to install and use the Specctra Router plugin on their respective websites or documentation pages.
How to Use Specctra Router
Once you have downloaded Specctra Router, you can use it to route your PCB layout in a few simple steps:
Export your PCB layout as a DSN file from your CAD tool.
Open Specctra Router and select your DSN file.
Set up your routing parameters, such as layer stackup, design rules, routing modes, etc.
Start the auto-router and wait for it to finish.
Save your routed board as a SES file from Specctra Router.
Import your SES file back to your CAD tool and check the results.
You can also use Specctra Router for manual routing or interactive routing, where you can control the routing process by using commands, mouse clicks or keyboard shortcuts. You can find more information on how to use Specctra Router in its online help or manual.
Specctra Router is a powerful and easy-to-use auto-router for PCB design that works with many CAD tools. It can help you save time and improve the quality of your PCB layout by automatically routing traces according to your design rules and constraints. You can download Specctra Router either as a standalone application or as a plugin for your CAD tool, depending on your preference. You can then use it to route your PCB layout in a few simple steps or interactively control the routing process.
