GENLIB_LOCON.3(October 1, 1997) 		 GENLIB_LOCON.3(October 1, 1997)

NAME
     GENLIB_LOCON - adds a logical connector to the current netlist figure

SYNOPSIS
     #include <genlib.h>
     void GENLIB_LOCON(connector, direction, signal);
     char *connector, *signal;
     char direction;

PARAMETERS
     connector		 Name of the connector to be created in the current fig-
			 ure

     direction		 Indicates  the  connector  behaviour  regarding signals
			 propagation

     signal		 Name of the signal on which the connector is linked

DESCRIPTION
     LOCON add a logical connector to the interface of the actual  working  fig-
     ure. This connector is logicaly linked to the signal signal.  The direction
     attribut may take the following values:

     IN     as input.

     OUT    as output.

     INOUT  as input/output, like supplies or clock for example.

     UNKNOWN
	    if one doesn't know what it is.

     TRISTATE
	    as high impedance output.

     TRANSV
	    as transciever. That means TRISTATE input plus output.

ERROR
     "GENLIB_LOCON impossible : missing GENLIB_DEF_LOFIG"
	    No figure has been yet specified by a call to DEF_LOFIG. So it isn't
	    possible  to  add anything. you must call DEF_LOFIG before any other
	    netlist call.
     "GENLIB_LOCON : Bad signal or connector bus name"
	    A signal or connector, described under a bus form,	has  an  illegal
	    syntax.

     "GENLIB_LOCON : All LOCON should be defined befor any GENLIB_LOINS"
	    A  connector  is added after instances. This is a methodological er-
	    ror.  Only move your LOCON before the first LOINS in your code.
     "GENLIB_LOCON : different number of signals and connectors"
	    A bussed form of signal and connector has been used, but  the  width
	    of the busses are not equal. This is an obvious error, check it.
     "Illegal addlocon. Connector connector already exist in figure figname"
	    A connector name must be unique in a given figure at a given hierar-
	    chy level.

DIAGNOSTICS
     Due to the vti file format, the direction of connectors is lost if one uses
     it  as starting point of a netlist desciption. All the connectors have then
     the UNKNOWN direction.
     Alliance and edif file format know only about IN, OUT, and  UNKNOWN.   Only
     vhdl format fully supports the whole thing.

EXAMPLE
     #include <genlib.h>
     main()
     {
	  /* Create a figure to work on  */
	  GENLIB_DEF_LOFIG("mycell");
	  /* define interface  */
	  GENLIB_LOCON("i", INPUT, "sig1");
	  GENLIB_LOCON("o", OUTPUT, "sig2");
	  /* Place an instance */
	  GENLIB_LOINS("model","instance", "sig1", "sig2", EOL);
	  /* Save all that on disk */
	  GENLIB_SAVE_LOFIG();
     }
