NAME¶

GENLIB_PLACE_CON_REF - put a connector on top of a reference belonging an instance in the current figure

SYNOPSYS¶

#include <genlib.h>
void GENLIB_PLACE_CON_REF(insname, refname, conname, layer, width, face)
char  ∗insname, ∗refname, ∗conname;
char layer, face;
long width;

PARAMETERS¶

insname

Name of the instance in the which the reference is to be searched for

refname

Name of the reference to be used for the connector placement

conname

Name of the connector to be placed

layer

Physical layer of the connector

width

Width of the connector

face

Face of the figure on which the connector is to be placed

DESCRIPTION¶

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:

NORTH

for a connector placed on the top of the cell.

SOUTH

for a connector placed on the bottom of the cell.

EAST

for a connector placed on the right side of the cell.

WEST

for a connector placed on the left side of the cell.

ERRORS¶

"GENLIB_PLACE_CON_REF impossible : missing GENLIB_DEF_PHFIG"

EXAMPLE¶

#include <genlib.h>
main()
{
	/∗ Create a figure to work on  ∗/
	GENLIB_DEF_PHFIG("cell");
	GENLIB_PLACE("gaci0_b", "r1", NOSYM, 23L, 54L);
	/∗ Put a reference ∗/
	GENLIB_PLACE_CON_REF("r1", "a_0", ALU2, 2, NORTH);
	/∗ Save that on disk ∗/
	GENLIB_SAVE_PHFIG();
}
