NAME

GENLIB_PHCON - place a physical connector in the current figure at absolute coordinates

SYNOPSYS

#include <genlib.h>
void GENLIB_PHCON(layer, width, name, orient, x, y)
char layer;
long width;
char ∗name, orient;
long x, y;

See the file buster/alliance/alc_origin.1.en.gz.

PARAMETERS

layer

Layout layer of the connector

width

Width of the connector

name

Name to be given to the connector

orient

Face of the cell on witch the connector belongs

x, y

Absolute coordinates of the connector

DESCRIPTION

PHCON adds a connector in the current layout cell, at the specified coordinates, with the given attributs. The layer argument can take the following legal values:

The name argument is not enough of an information to non ambigiously identify a connector. In order to be able to do so, an index is computed for each connector that has an already existing name, following a topological order. Each time a connector is created, the index is updated, regarding the name of the connector. Since someone writting a tiler needs to know exactly what connector to access, the indexation algorithm must be known by the user.

Connectors with a unique name:

Such connectors have the index 0

Connectors with a name apearing many times:

The indexes are computed from left to right, and then from bottom to top, starting at 0. If two connectors are on the same location, with the same name, then the layer decides which one is has the greater number, from lower level, NWELL to upper level, ALU3.

The orient paramater may take 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.

Remark:

Connectors placed on corners of leaf cells are given the EAST orientation if on top/right or bottom/right corner, and WEST if top/left or bottom/left.

ERRORS

"GENLIB_PHCON impossible : missing GENLIB_DEF_PHFIG"

EXAMPLE

#include <genlib.h>
main()
{
	/∗ Create a figure to work on  ∗/
	GENLIB_DEF_PHFIG("cell");
	.
	.
	.
	GENLIB_DEF_AB(0L, 0L, 0L, 0L);
	/∗ Put a connector ∗/
	GENLIB_PHCON(ALU1, 1, "cin", SOUTH, 12L, 0L);
	/∗ Save that on disk ∗/
	GENLIB_SAVE_PHFIG();
}
