INPUT_ACLR_B
String No Specifies the asynchronous
clear port for the
datab[]
port. Values are
ACLR0
,
ACLR1
,
ACLR2
, and
ACLR3
. If
omitted the default value is
ACLR3
.
INPUT_REG_A
String No Specifies the clock port for
the
dataa[]
port. Values are
UNREGISTERED
,
CLOCK0
,
CLOCK1
,
CLOCK2
, and
CLOCK3
.
If omitted, the default value is
CLOCK0
.
INPUT_REG_B
String No Specifies the clock port for
the
datab[]
port. Values are
UNREGISTERED
,
CLOCK0
,
CLOCK1
, and
CLOCK2
. If
omitted, the default value is
CLOCK0
.
INTENDED_DEVICE_FAMILY
String No This parameter is used for
modeling and behavioral
simulation purposes. Create
the ALTMULT_ACCUM
megafunction with the
MegaWizard Plug-In
Manager to calculate the
value for this parameter.
LPM_HINT
String No
When you instantiate a
library of parameterized
modules (LPM) function in a
VHDL Design File (.vhd),
you must use the
LPM_HINT
parameter to specify an
Altera-specific parameter.
For example:
LPM_HINT =
"CHAIN_SIZE = 8, ONE_
INPUT_IS_CONSTANT = YES"
The default value is
UNUSED
.
LPM_TYPE
String No Identifies the library of
parameterized modules
(LPM) entity name in VHDL
design files.
