man GENLIB_LOCON (1): adds a logical connector to the current netlist figure

SYNOPSYS

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

man2html: unable to open or read file man1/alc_origin.1

PARAMETERS

connector: Name of the connector to be created in the current figure
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 figure. 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"

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();
