TopoR routes all connections, even if this entails violating design constraints. Routing of the wiring topology is done automatically and flexibly angles are not limited to 90° and 45°.Įfficient use of PCB space and absence of preferred routing directions in layers considerably reduces electromagnetic crosstalk. The resulting boards can be exported into Specctra/ELECTRA SES session files, DXF, Gerber, P-CAD PCB ASCII (2000, 2002, 2004), PADS PCB ASCII (3.5, 4.0, 5.0, 2005.0). TopoR imports input in Delta Design's FST format, as Specctra-/ ELECTRA-compatible DSN design files, or in P-CAD PCB ASCII (2000, 2002, 2004), PADS PCB ASCII (3.5, 4.0, 5.0, 2005.0), or EAGLE BRD XML formats (6.x). TopoR can be used as an external autorouter for third-party layout editors or in conjunction with Eremex's own schematic capture and layout editor Delta Design (DD).
#TOPOR AUTOROUTER SOFTWARE#
Since TopoR 4.1 (2008) the software is further developed and maintained by Eremex, Ltd.
TopoR 4.0 added support to import/export DSN design and SES session files. The software was commercially distributed by Prosoft Spb. TopoR was developed by a group called the FreeStyleTeam, supervised by Sergey J. The program routed not only dual-layer but also multi-layer printed circuit boards. TopoR 1.03 was available on and distributed through ElekTrade (ЭлекТрейд).
#TOPOR AUTOROUTER WINDOWS#
The first Windows version of the topological router was released in 2001 and renamed to TopoR. The last version of FSR for DOS, consisting of the router named SpeedWay and the layout editor named FreeStyle was version 1.6 as of /. The company also announced plans to commercially release a FreeStyle Suite for Windows later the year. A 1.44 MB floppy disk was enough for the program and accompanying examples. This early router showed the advantages of an innovative approach to routing and high efficiency of the models, algorithms, and software implementation. In 2002, the FreeStyle Router (FSR) by Диал Инжиниринг ("Dial Engineering") ran under DOS and successfully routed dual-layer boards, interfacing with P-CAD. ġ996 saw the release of the first version of a topological router that actually came to be used by industrial enterprises. Work on a flexible topological router began in 1988, when it became clear that the traditional methods of routing with regular and irregular grids ( grid-based routers and shape-based routers) and consecutive wiring with locked-down geometry were a dead-end solution.
