TopoR
automated topological router for printed circuit boards
TopoR (Topological Router) is an EDA program developed and maintained by the Russian company Eremex. It is dedicated to laying out a printed circuit board (PCB). The current version is 6.3.17875 as of 2017-09-20.
It features an autorouter and a set of tools intended to reduce the amount of effort needed for manual routing of a PCB. A distinctive feature of TopoR is the absence of preferred routing directions.
History
Work on a flexible topological router began in 1988.
1996 saw the release of the first version of a topological router that actually came to be used by industrial enterprises. In 2002, the FreeStyle Router (FSR) by Диал Инжиниринг ("Dial Engineering") ran under DOS and successfully routed dual-layer boards, interfacing with P-CAD. This early router showed the advantages of an innovative approach to routing and high efficiency of the models, algorithms, and software implementation. A 1.44 MB floppy disk was enough for the program and accompanying examples. The company also announced plans to commercially release a FreeStyle Suite for Windows later the year. 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 2003-09-26/2003-11-01.
Begin with the source’s own compact description: “TopoR” is automated topological router for printed circuit boards. The dossier treats that line as a proposition to test through TopoR, automated and topological, not as a finished interpretation.
Why this record matters
The phrase “automated topological router for printed circuit boards” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 11, 2026. The linked authority identifier is Q2443355. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2017, 1988, 1996 and 2002.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
