Parameter Name Type Required Description
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.
