NAME

       GENLIB_LOSIGMERGE - merge two logical signals

SYNOPSYS

       #include <genlib.h>
       void GENLIB_LOSIGMERGE(signal1, signal2)
       char *signal1, *signal2;

ORIGIN

       This  software  belongs	to  the  ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
       Paris, France.

PARAMETERS

       signal1		   Name of a signal to be merged

       signal2		   Name of a signal to be merged

DESCRIPTION

       LOSIGMERGE merges the two signals, signal1 and signal2.	This function can be used anywhere in  the  genlib  program,  but  its	resultings
       actions must be known by the user.

       1)	 If signal1 and signal2 have not been used yet, then the corresponding signal can be later accessed through any of these aliases.

       2)	 If  one  of signal1 or signal2 has not been used yet, then all further reference to the not defined name will be made on the same
		 signal than the defined signal.

       3)	 If both signals exist, then they are merged, and both can be used for reference to the same signal later on.

       Since most of the file formats do not allow multiple name for a single signal, the choice is made to keep for  disk  usage  the	name  that
       appears in the cell interface, if any.  Otherwise, the choice is randomly made by LOSIGMERGE.

       Warning	 This function allows the user to internally connect two external connectors.  This is not a valid disk representation for netlist
		 generated by genlib.  The SAVE_LOFIG function will exit if encountering such a situation.
		 In order to avoid it, either take care not to link such signals, or build all your hierarchy in memory, make sure your block does
		 not have such signals, and call FLATTEN_LOFIG(3) just before saving.

EXAMPLE

       #include <genlib.h>
       main()
       {
	    /* Create a figure to work on  */
	    GENLIB_DEF_LOFIG("cell");
	    /* Define interface *
	    GENLIB_LOCON(...
	    /* Place an instance */
	    GENLIB_LOINS("no2_y" ,"no3" ,"a8_s" ,"a9_s" ,"new_no3_s" ,"vdd" ,"vss" ,0);
	    GENLIB_LOINS("no2_y" ,"no4" ,"a12_s" ,"a15_s" ,"no4_s" ,"vdd" ,"vss" ,0);
	    GENLIB_LOINS("a2_y" ,"a22" ,"no3_s" ,"no4_s" ,"a22_s" ,"vdd" ,"vss" ,0);
	    GENLIB_LOSIGMERGE("new_no3_s", "no3_s");
	    /* Save all that on disk */
	    GENLIB_SAVE_LOFIG();
       }

NAME

       GENLIB_LOSIG - declare an internal logical signal, or a vector of internal logical signals

SYNOPSYS

       #include <genlib.h>
       void GENLIB_LOSIG(name)
       char *name;

ORIGIN

       This  software  belongs	to  the  ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
       Paris, France.

PARAMETERS

       name		   Name of a signal to be declared

DESCRIPTION

       LOSIG creates the internal signal, or the set of internal signals coresponding to a vector description, represented by  name.   See  BUS(3)
       and ELM(3) for more details on vectors.
       The  need  for declaring signal is mostly felt when one wants to create a consistent vector declaration, for file formats that do not allow
       partial or multiple declarations, like vhdl.  This way, a user can create a vector and access its member the way he wants, but still having
       an internal consistent form.

       Warning		   If  a signal is declared with LOSIG, but not used, the resulting file will have an internal node floating.  This is not
			   an error from a genlib point of view, so the user must be aware of it.

EXAMPLE

       #include <genlib.h>
       main()
       {
	    /* Create a figure to work on  */
	    GENLIB_DEF_LOFIG("cell");
	    /* Define interface *
	    GENLIB_LOCON(...
	    /* declare buses */
	    GENLIB_LOSIG("grum[23:0]");
	    GENLIB_LOSIG("iconection[0:7]");
	    /* Place an instance */
	    GENLIB_LOINS("no2_y" ,"no3" ,"grum[12]" ,"a9_s" ,"new_no3_s" ,"vdd" ,"vss" ,0);
	    GENLIB_LOINS("no2_y" ,"no4" ,"a12_s" ,"grum[6]" ,"no4_s" ,"vdd" ,"vss" ,0);
	    GENLIB_LOINS("a2_y" ,"a22" ,"no3_s" ,"grum[15]" ,"a22_s" ,"vdd" ,"vss" ,0);
	    /* Save all that on disk */
	    GENLIB_SAVE_LOFIG();
       }
