in May 1997. Since its integration into Cadence's Allegro PCB Editor, the name of the router is Allegro PCB Router. The latest version is 17.4 – 22.1 (20 October 2022). Specctra routes boards by presenting graphical data using a "shape-based" technology which represents graphical objects not as a set of points-coordinates but more compact. This increases the efficiency of routing printed circuit boards with a high density of components, provides automatic routing of the same chain of tracks of different widths, and more. Specctra uses adaptive algorithms implemented in multiple trace runs. The routing is carried out in three stages: # preview routing # autoroute # additional processing of autoroute results On the first pass, the connection of all conductors is performed, regardless of the presence of conflicts, which consist in crossing the conductors on one layer and breaking the gaps. On each subsequent pass, the auto-router tries to reduce the number of conflicts by breaking and re-building connections (the

s for printed circuit boards, thanks to the use of industrial-standard DSN design file format for project description and Do-files to specify routing strategies. The results are returned to the board editor via SES session files as well as RTE files. Protocol command execution is recorded in Did-file, which after editing can be used as new Do-files. The DSN/SES file formats are also supported by a number of other auto-routers including KONEKT ELECTRA,
