write_def [filename]
where filename is the name to give to the DEF format output file. If not specified, the name of the output DEF file will be the root name of the input DEF file plus "_routed.def".
The write_def command writes a DEF format file that is an annotated version of the DEF format file given to qrouter as input, with the nets in the NETS section annotated with physical route information, and the optional addition of a SPECIALNETS section describing the geometry of stub routes connecting route grid points to off-grid terminals.
write_def is implemented as a built-in command in qrouter.
