$add_or_replace_instance()
As a library developer, you should write a function that does exactly what you
want it to do. The $add_or_replace_instance() function can serve as a guide if it
does some or most of what you want. Once you have written your function, call it
from your own menus. The pathname to the file in which the
$add_or_replace_instance() function is defined is:
$MGC_HOME/shared/pkgs/da_ic/userware/$LANG/schematic.ample
Copy the function to your own schematic.ample file, and edit the function to
match your needs. Be sure to give the edited function a unique name; DO NOT
name it “$add_or_replace_instance()”. Also, user-defined functions should not
begin with “$”. If you do not rename the function, your function will overwrite the
one supplied by Mentor Graphics, and the Mentor Graphics menu will not work
correctly.
The following is a short version of the $add_or_replace_instance() function.
function sample_add_or_replace_instance( comp : string,
smbl : optional string { default = "" }
), INDIRECT
{
if ($does_component_exist(comp) != "") {
$set_active_symbol(comp,smbl);
if (session_area@@$instance_replacement_mode == @off)
$place_active_symbol();
else
$$replace(comp,smbl,@clear);
$set_instance_replacement_mode(@off);
else
$message($format("Cannot find component %s. Please
ensure logical name is defined or have the component
installed.",comp),@warning);
}
Keep in mind that the $add_or_replace_instance() function is only a guide; it is
not meant to be used “as is” by library developers. It was written specifically to be
called by the Mentor Graphics gen_lib menus. Notice that the function exists only
in the file in which it is used as a call from the menus defined by the same group.
