cleanup
where there are no options to the command.
The cleanup command performs a sweep of the design for vias on the same net, placed on adjacent track positions where such a placement violates the DRC rule for distance between vias. In those cases, without the ability for any other route to be passed between the vias, one of the vias can be removed, and the route attached to that via given an L-bend to reach the other via.The cleanup should be performed after all routing has been completed but before any output is generated, including delay generation, DEF output, and antenna fixes, as these are all dependent upon route topology and may be altered due to the modifications made by the cleanup command.
cleanup is implemented as a built-in command in qrouter.
