PHREF(3) MBK PHYSICAL STRUCTURE DEFINITIONS PHREF(3) NAME phref - mbk physical reference DESCRIPTION The phref structure is used to describe a reference belonging to a sym- bolic layout model, see phfig(3) for details. A reference allows to name a point anywhere in a given model. It may then be seen as a name, and not anymore as a couple of coordinates. References are mostly used for cell programming and multi-access connector representation. The declarations needed to work on phref are available in the header file "/labo/include/mph402.h", where '402' is the actual mbk version. The following C structure supports the description of the reference : typedef struct phref { struct phref *NEXT; char *FIGNAME; char *NAME; long XREF,YREF; struct ptype *USER; } phref_list; NEXT Pointer to the next reference in the list. FIGNAME Kind of reference. Gives information about the pos- sible uses of the object. Some FIGNAME are in use today : "ref_con" for multi-access connectors "ref_ref" for all other uses NAME Name of the reference. The reference is identified by its name, so it should be unique at a given hi- erarchical level. XREF, YREF Coordinates of the point being referenced. USER Pointer to a ptype list, see ptype(3) for details, that is a general purpose pointer used to share in- formation on the reference.
