# phcon(3)

mbk physical connector

## NAME

phcon - mbk physical connector

## DESCRIPTION

The **phcon** structure is used to describe a connector belonging to a symbolic layout model, see [**phfig**(3)](/phfig/3.md) for details. A strong convention on the mbk data structure is that two connector internally wired have the same name, the 'logical' name.

The declarations needed to work on **phcon** are available in the header file *"/labo/include/mph402.h"*, where '*402*' is the actual mbk version.

The following C structure supports the description of the connector :

```
typedef struct phcon {
	struct phcon	∗NEXT;
	char	∗NAME;
	long	INDEX;
	long	XCON, YCON;
	long	WIDTH;
	char	ORIENT;
	char	LAYER;
	struct ptype	∗USER;
} phcon_list;
```

- *NEXT*

  Pointer to the next connector of the model.

- *NAME*

  Name of the connector. A model may posseses more than one connector with a given name, if they are internally wired.

- *INDEX*

  Index of the connector. Since a model may have many connectors with the same name, it is needed to be able to point out one of them. The index allows to distinguish every connector using a topological order. This field is filled by the **addphcon** function, and shall not be modified otherwise.

- *XCON, YCON*

  Connector coordinates. the point *(XCON, YCON)* must be placed on or inside of the *abutment box* of the model.

- *ORIENT*

  Caracter indicating the face of the model on the which the connector is placed. It may take four values :

  - **NORTH**

    connector placed on top of cell

  - **SOUTH**

    connector placed on bottom of cell

  - **EAST**

    connector placed on right of cell

  - **WEST**

    connector placed on left of cell

- *LAYER*

  Symbolic layer used for the connector. The legal values are :

  - **NWELL**

    N bulk

  - **PWELL**

    P bulk

  - **NTIE**

    N implant in P bulk

  - **PTIE**

    P implant in N bulk

  - **NDIF**

    N diffusion

  - **PDIF**

    P diffusion

  - **NTRANS**

    N transistor

  - **PTRANS**

    P transistor

  - **POLY**

    polysilicium

  - **ALU1**

    first metal

  - **ALU2**

    second metal

  - **ALU3**

    third metal

  - **TPOLY**

    polysilicum through route

  - **TALU1**

    first metal through route

  - **TALU2**

    second metal through route

  - **TALU3**

    third metal through route

- *WIDTH*

  Width of the connector. The physical extension, concerning the width, of a connector is paralell to its face.

- *USER*

  Pointer to a ptype list, see **ptype** for details, that is a general purpose pointer used to share informations on the connector.
