GENLIB_WIRE1 — place a physical segment in the current figure

Synopsis

#include <genlib.h>
void GENLIB_WIRE1(layer, width, ins1, con1, index1, ins2, con2, index2)
char layer;
long width;
char ∗ins1, ∗con1, ∗ins2, ∗con2;

Parameters

layer

Layout layer of the segment

width

Width of the segment

ins1

Name of the instance in which the connector con1 is to be looked for

con1

Name of a connector, or reference, used as first endpoint of the wire

ins2

Name of the instance in which the connector con2 is to be looked for

con2

Name of a connector, or reference, used as last endpoint of the wire

Description

WIRE1 adds a segment made of the layer level in the current layout cell, the starting point being the connector, or reference, con1 of the instance ins1, and the ending point being the connector, or reference, con2 of the instance ins1. The segment is drawn between the coordinates of con1 in the current figure and the coordinates of con2 in the current figure.

If the endpoints are connectors, the indexes index1 and index2 must respectivly refer to con1 and con2. If they are references, then they are not taked care of. One shall notice that connectors and references of a given model should not share names if WIRE1 is to be used.

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

Errors

"GENLIB_WIRE1 impossible : missing GENLIB_DEF_PHFIG"

No figure has been yet specified by a call to DEF_PHFIG. So it isn't possible to place an instance inside it. you must call DEF_PHFIG before any other layout action.

"illegal addphseg : x1, y1, x2, y2"

A symbolic segment must be either vertical or horizontal, so either x1 = x2, or y1 = y2. Since WIRE1 creates a segment from relative coordinates, care must be taken to follow the previous rule.

"GENLIB_WIRE1 impossible : same name conX, for connector and reference in insX"

The model of the instance insX has both a connector and a reference that matches the conX name. This is not legal since genlib doesn't know which one to choose as point.

"illegal getphins : instance insX does not exist"

The instance called insX does not currently belong to the figure.

Example

#include <genlib.h>
main()
{
	/∗ Create a figure to work on  ∗/
	GENLIB_DEF_PHFIG("cell");
	GENLIB_PLACE("gaci0_b", "r_addin_1", NOSYM, 0, 0);
	GENLIB_PLACE_RIGHT("gapgn_b", "pg", NOSYM);
	GENLIB_PLACE_RIGHT("gacin_b", "r_addin_2", NOSYM);
	/∗ Draw a segment ∗/
	GENLIB_WIRE1(ALU1, 1, "r_addin_1", "out", 0L, "r_addin_2", "in", 1L);
	/∗ Save that on disk ∗/
	GENLIB_SAVE_PHFIG();
}
