PLACE_SEG_REF places a segment regarding the position of the reference, refname, in the instance called insname. The segment 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 the segment is not added, since it would have zero as length
the reference is anywhere else
A segment is drawn between the reference and the abut_ment
box, and is given layer and width as attributs.
One of its endpoint is given by the reference coordinates,
the other one comes from the face. The face
argument is meant in the placed instance, and can take
any of the following values:
PLACE_SEG_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_SEG_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_SEG_REF impossible : no abutment box"
The current figure does not have an abutment box. Use DEF_AB(3)
before this function.
illegal PLACE_SEG_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.
