Description
OUTPUT_SATURATION
String
No
Enables saturation handling at
second adder stage. If original
design uses a Stratix II device, in
some cases this parameter can be
derived from the Stratix II
rounding settings. Values are
YES
,
NO
, and
VARIABLE
. A value of
YES
or
NO
specifies saturation
handling setting permanently to
on or off. A value of
VARIABLE
allows dynamically controlled
saturation handling. If omitted,
the default value is
NO
.
OUTPUT_SATURATE_REGISTER
String
No
Specifies the clock source for the
first register on the
output_
saturate
input. Values are
UNREGISTERED
,
CLOCK0
,
CLOCK1
,
CLOCK2
, and
CLOCK3
. If omitted,
the default value is
UNREGIS-
TERED
.
OUTPUT_SATURATE_ACLR
String
No
Specifies the asynchronous clear
source for the first register on the
output_saturate
input. Values
are
ACLR0
,
ACLR1
,
ACLR2
, and
ACLR3
. If omitted and
OUTPUT_
SATURATE_REGISTER
is used, the
default value is
ACLR3
.
OUTPUT_SATURATE_PIPELINE_REGISTER
String
No
Specifies the clock source for the
second register on the
output_
saturate
input. Values are
UNREGISTERED
,
CLOCK0
,
CLOCK1
,
CLOCK2
, and
CLOCK3
. If omitted,
the default value is
CLOCK0
.
OUTPUT_SATURATE_PIPELINE_ACLR
String
No
Specifies the asynchronous clear
source for the second register on
the
output_saturate
input.
Values are
ACLR0
,
ACLR1
,
ACLR2
,
and
ACLR3
. If omitted and
OUTPUT_SATURATE_ PIPELINE_
REGISTER
is used, the default
value is
ACLR3
.
