Specctra uses adaptive algorithms implemented in multiple trace runs.
On each subsequent pass, the auto-router tries to reduce the number of conflicts by breaking and re-building connections (the ripup-and-retry router method) and pushing the conductors by pushing the neighboring ones (the push-and-shove router method).
Electromagnetic compatibility can be tested in Specctra through the "SPECCTRAQuest SI Expert" module.
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,[7] Eremex TopoR,[8] Alfons Wirtz's FreeRouting[9] and RL-based DeepPCB.
