NAME

       DECLAR, GENPAT Package

SYNOPSYS

       DECLAR("ident",":nb_space","format",mode,size,option);

PARAMETERS

       ident     External  connector,  internal  observing  points  or  register's  name.  For  the hierarchical
                 descriptions, the path-name of the internal observing points or registers must be specified  by
                 the syntax : instance1.instance11.name .

       nb_space  Specify  the  number  of  blank space between each group of value associated to the connectors,
                 signals or registers in the output file. 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,
                 signals or registers. X for Hexadecimal, O for Octal and B for Binary.

       mode      Specify  the  type  of  the  connectors.  IN for Input, OUT for Output, INOUT for Input/Output,
                 SIGNAL for internal observing point, REGISTER for register. IN, OUT,  INOUT,  SIGNAL,  REGISTER
                 are constants (defines) provided by genpat.

       size      Specify  the size of the bused connectors : empty ("") for the scalar connectors, "nb1" for the
                 numbered connectors, "nb1 TO nb2" or "(nb1 TO nb2)" (nb1 < nb2),  "nb1  DOWNTO  nb2"  or  "(nb1
                 DOWNTO nb2)" (nb2 < nb1) for the vectors. Where nb1 and nb2 are integer.

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

DESCRIPTION

       Describes a set of connectors, signals or registers of the same format, size and mode.

EXAMPLE

       DECLAR("a", ":2", "X", OUT, "3 DOWNTO 0", "S");

       describes : a 3, a 2, a 1, a 0
       format    : Hexadecimal.
       mode      : Output.
       option    : Spied connector.

       the group is separated of the others with 2 blank spaces.
       result :
            out a(3 downto 0) X spy ;;;

       DECLAR ("toto", ":", "O", INOUT, "7 TO 11", "");

       describes : toto 7, toto 8, toto 9, toto 10, toto 11.
       format    : Octal.
       mode      : Input/Output.
       option    : none.

       the group is separated of the following with 0 blank space.
       result :
            inout toto(7 to 11) O ;

       DECLAR ("ck", ":2", "B", IN, "", "");

       describes : ck.
       format    : Binary.
       mode      : Input.
       option    : none.

       the port is separated of the following with 2 blank spaces.
       result :
            in ck ;;;

       DECLAR ("accu.f", ":", "B", SIGNAL, "", "S");

       describes : accu.f .
       format    : Binary.
       mode      : Signal.
       option    : Spied connector.

       the signal is separated of the following with 0 blank space.
       result :
            signal accu.f spy ;

       DECLAR ("accu.reg", ":1", "B", REGISTER, "(3)", "");

       describes : accu.reg .
       format    : Binary.
       mode      : Register.
       option    : none.

       the signal is separated of the following with 1 blank space.
       result :
            register accu.reg(3) ;;;;

WARNING

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