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.
