Description

EXTRA_LATENCY String No Specifies the number of clock

cycles of latency.

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.

INTENDED_DEVICE_FAMILY String No This parameter is used for

modeling and behavioral

simulation purposes. Create the

ALTMULT_ADD megafunction

with the MegaWizard Plug-in

Manager to calculate the value for

this parameter.

DSP_BLOCK_BALANCING String No If omitted, the default value is

AUTO.

DEDICATED_MULTIPLIER_CIRCUITRY String No Specifies whether to use the DSP

block to implement the circuit.

Values are YES, NO, and AUTO. The

circuit is implemented using the

DSP block when the value is set

to YES. If omitted, the default

value is AUTO.
