PLACE_CON_REF places a connector called conname ragarding the position of
the reference, refname, in the instance called insname. The connector
coordinates are computed from the reference coordinates and the face given
as argument.
Two behaviours are expected, regarding the reference coordinates:
the reference is on the given face of the abutment box a connector called conname is added on top of the reference, with the given layer and width.
the reference is anywhere else
a connector called conname is added on the given face,
face, of the abutment box, at the y coordinates of the
reference if the face is EAST or WEST, or x one if the
face is NORTH or SOUTH. Then a segment is drawn
between the reference and the connector. All drawn
objects are given layer and width as caracteristics.
The face argument is meant in the placed instance, and
can take any of the following values:
PLACE_CON_REF impossible : missing DEF_PHFIG"
No figure has been yet specified by a call to DEF_PHFIG. So it
isn't possible to place a reference inside it. you must call
DEF_PHFIG before any other layout action.
PLACE_CON_REF impossible : missing DEF_PHFIG"
No figure has been yet specified by a call to DEF_PHFIG. So it
isn't possible to place a reference inside it. you must call
DEF_PHFIG before any other layout action.
PLACE_CON_REF impossible : no abutment box"
The current figure does not have an abutment box. Use DEF_AB(3)
before this function.
illegal PLACE_CON_REF : orientation is XX"
The face parameter does not have a legal value, but XX.
illegal getphins : instance called insname does not exist"
No instance called insname exists in the current figure
illegal getphref : references called refname does not exist"
No reference called refname exists in the model of the instance
insname.
