Parameter Name Type Requi

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.
