SYNOPSYS






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


[Include document man1/alc_origin.1]

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:
NWELL
PWELL
NTIE
PTIE
NDIF
PDIF
NTRANS
PTRANS
POLY
ALU1
ALU2
ALU3
TPOLY
TALU1
TALU2
TALU3

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"
No figure has been yet specified by a call to DEF_PHFIG. So it isn’t possible to place a connector inside it. you must call DEF_PHFIG before any other layout action.
"illegal addphcon : orientation is XX in name"
The orient parameter does not have a legal value, but XX.

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();
}
