The REPLACE command has two different modes that are chosen by the SET command. In both modes it is possible to substitute a component with another component.
The first mode (default) is activated by the command:
SET REPLACE_SAME NAMES;
In this mode the new package must have the same pad and smd names
as the old one. It may be taken from a different library and it may
contain additional pads and smds. The position of pads
and smds is irrelevant.
Pads of the old package connected with signals must be present in the new package. If this condition is true the new package may have less pads than the old one.
The second mode is activated by the command
SET REPLACE_SAME COORDS;
In this mode, pads and smds of the new package must
be placed at the same coordinates as in the old one (relative to the
origin). Pad and smd names may be different. The new package may be
taken from a different library and may contain additional pads and
smds.
Pads of the old package connected with signals must be present in the new package. If this condition is true the new package may have less pads than the old one.
REPLACE functions only when the appropriate tOrigins/bOrigins layer is displayed.
