PHCON(3) MBK PHYSICAL STRUCTURE DEFINITIONS PHCON(3) NAME phcon - mbk physical connector DESCRIPTION The phcon structure is used to describe a connector belonging to a symbolic layout model, see phfig(3) 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 distin- guish 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, con- cerning the width, of a connector is parallel to its face. USER Pointer to a ptype list, see ptype for details, that is a general purpose pointer used to share information on the connector.
