PARAMETERS

type

Type of the reference to be added

name

Name of the reference

x, y

Absolute coordinates of the reference

DESCRIPTION

PHREF adds a reference in the current layout cell, at the specified coordinates. A reference is an object that allows to symbolicaly name a point for futur use by the designer. They have been mainly used in the past to program decoders, in order to obtain many cells from a unique cell.

The type argument may take the two following legal values:

ref_con

for virtual connectors, see dpr(1) for details.

ref_ref

for any other need from the designer.

ERRORS

"GENLIB_PHREF impossible : missing GENLIB_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.

EXAMPLE

 #include <genlib.h>
 main()
 {
         /* Create a figure to work on  */
         GENLIB_DEF_PHFIG("cell");
         .
         /* Put a reference */
         GENLIB_PHREF("ref_con", "in_a[0]", 102L, 10L);
         .
         .
         GENLIB_DEF_AB(0L, 0L, 0L, 0L);
         /* Save that on disk */
         GENLIB_SAVE_PHFIG();
 }
