+Gsch2pcb-rnd is a standalone utility that can extract netlists and +element data from a schematics produced by gschem. Thus it is a glue +between gschem and pcb-rnd, doing forward annotation. It is ideal +for automating the design process as it can be easily called from +Makefiles, shell scripts or other programs/scripts, whereas the +"import schematics" feautre (import_sch plugin) is more geared for the +GUI user. +
+Multiple methods of operation are offered - the user can select +one of these by name, using the -m command line argument (e.g. +gsch2pcb-rnd -m importsep foo.sch): +
| method name + | description + |
| pcb + | The classic approach: load the existing extract elements from + the .sch file, load the .pcb file, compare element lists, load + footprint libraries and create .new.pcb and .net and .cmd and let + the user handle the rest. Does not work with anything else + than the .pcb format. This method is deprecated and is + provided only for compatibility with some old workflows. + |
| import + | Runs the same gnetlist backend as the import_sch plugin. A single + action command file generated with .cmd suffix. When executed + (using action ExcuteFile(foo.cmd)), it syncs (replaces/creates) + every element and sets up all nets. Pro: single-command import. + Con: can't load netlist only or elements only. + |
| importsep + | Similar to import, but produces two files: a .cmd file with element + updates only (can be appled the same way as import's) and a + separate .net netlist file that can be imported the same way as the + .net of the pcb method. Pro: the user can update elements-only or + nets-only. Con: requires two user actions to get a full impoty. + |
