ARRAY(3)		       GENPAT functions			      ARRAY(3)

NAME
       ARRAY, GENPAT Package

SYNOPSYS
       ARRAY ("ident", "ident",	..., ":nb_space", "format", type, option, "ident_group", 0);

PARAMETERS
       ident	 Name,	followed with a	number if part of a bused signal, of a
		 connector, a signal or	a register. All	idents must be of  the
		 same  type.  The  name	 and the number	must be	separated by a
		 blank or the number must be parenthesized.

       nb_space	 Specify the number of	blank  space  between  each  group  of
		 value.	0,1,2,3,4,5,6, 7,8,9 or	nothing.

       format	 Specify  the  format that will	be used	to represent the value
		 associated to the connectors. X for Hexadecimal, O for	 Octal
		 and B for Binary.

       type	 Specify  the  type  of	 the aggregate.	REGISTER for Register,
		 SIGNAL	for Signal, OUT	for Output, IN for  Input,  INOUT  for
		 Input/Output.	REGISTER, SIGNAL, OUT, IN, INOUT are constants
		 (defines) provided by genpat.

       option	 Specify options of the	connectors. "S"	for a spied connector,
		 empty ("") for	a normal connector.

       ident_group
		 Specify  the array's name, the	first ident is associated with
		 the MSB of the	array.

DESCRIPTION
       Create a	virtual	vector with signals of the same	type and  format.  The
       signals may be either Inputs, Outputs, Inputs/Outputs, Registers	or In-
       ternal Signals.	A vector to be aggregate is to be declared bit per bit
       (it  will  appear as a vector in	the output file). Outputs, Signals and
       Registers can be	redeclared in a	virtual	vector.	Inputs and Inputs/Out-
       puts CANNOT be redeclared.

EXAMPLES
       ARRAY ("cout", "s 9", "s	8", "s 7", ":2", "B", OUT, "S",	"Y", 0);

       format :	Binary.
       type   :	Output connector.
       option :	spied connector.

       each group is separated of the others with 2 blank spaces.
       result :	  out Y	( cout,	s (9 downto 7) ) B spy ;;;

       ARRAY ("regt", "reg 9", ":2", "B", REGISTER, "",	"Y", 0);

       format :	Binary.
       type   :	Register.
       option :	none.

       each group is separated of the others with 2 blank spaces.
       result :	  register   Y ( regt, reg (9 downto 9)	) B;;;

WARNING
       The ARRAY function from the 4.0 release have a new parameter (option).

DIAGNOSTICS
       You  are	 dealing with a	variable number	of parameters fonction.	If you
       forget one or more parameter, you will have one of  the	following  re-
       sults :

	      Nothing bad happen, but your result file is erroneous.
	      You are asked for	more parameter.
	      You crash	the program and	produce	a Segmentation Fault.

       In all cases, check your	C file for missing parameter.
