# DECLAR(3)

## 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).
