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 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;;;
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 results :
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.
