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.
