This software is an incredibly fast and comprehensive PCB autorouter that utilizes free-angle technology and arc-like traces for superior results. It outperforms shape-based autorouters and tedious manual routing methods.
TopoR is an extremely fast and comprehensive topological PCB autorouter that utilizes free-angle technology to make arc-like traces. This results in a far superior outcome compared to shape-based auto-routers or manual routing that can be time-consuming. TopoR supports the Specctra DSN/SES interface to exchange data with PCB CAD packages, and a 650 pin version is available for free.
Compared to other auto-routers, TopoR routes with fewer vias/layers and has shorter lengths of traces. Each wire is given a minimal length and goes around pads with proper clearance. There is no preferred routing direction in layers, which significantly reduces wire parallelism and electromagnetic crosstalks.
TopoR has an intuitive user interface that allows beginners to learn and create their first free-angle design in just a few hours. Tips are displayed before all operations to help with the routing process. The user manual and tutorials guide you through the entire process, making it easy to get started.
TopoR can perform parallel optimization of several alternative topology variants that differ in optimized parameters. The user is offered a choice of selecting one or several variants. One of the unique features of TopoR is its ability to move components on the routed board while preserving the connections' topology. Geometry and positioning of components are automatically calculated to comply with the new components' position.
Movement of components, vias, and wire branching is used to decrease wire length and provide ample clearance space. The movement can be performed both manually and automatically, and the most effective wire shapes are defined immediately.
Due to the absence of a preferred routing direction in layers and the deep level of optimization, TopoR provides high-quality routing of contemporary BGA components. This is traditionally a very difficult problem for other routers, but TopoR handles it with ease.
