NAME

DECLAR, GENPAT Package

See the file man1/alc_origin.1.

SYNOPSIS

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).
