ARRAY.3alc - Man Page

ARRAY, GENPAT Package

Synopsis

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.

Create a virtual vector with signals of the same type and format. The signals may be either Inputs, Outputs, Inputs/Outputs, Registers or Internal 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/Outputs 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;;;
