The following table lists the parameters for the LPM_DIVIDE megafunction.
Parameter Name
Type
Required
Description
LPM_WIDTHN
Integer
Yes
Specifies the widths of the
numer[]
and
quotient[]
ports. Values are
1
to
64
.
LPM_WIDTHD
Integer
Yes
Specifies the widths of the
denom[]
and
remain[]
ports. Values are
1
to
64
.
LPM_NREPRESENTATION
String
No
Sign representation of the numerator
input. Values are
SIGNED
and
UNSIGNED
. When this parameter is set
to
SIGNED
, the divider interprets the
numer[]
input as signed two's
complement.
LPM_DREPRESENTATION
String
No
Sign representation of the
denominator input. Values are
SIGNED
and
UNSIGNED
. When this parameter is
set to
SIGNED
, the divider interprets
the
denom[]
input as signed two's
complement.
LPM_TYPE
String
No
Identifies the library of parameterized
modules (LPM) entity name in VHDL
design files (.vhd).
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
.
