Description
PORT_OUTPUT_IS_OVERFLOW
String
No
Specifies port usage. Values are
PORT_UNUSED
and
PORT_USED
.
When the value is set to
PORT_
USED
, output pin overflow is
added. If omitted, the default
value is
PORT_UNUSED
.
PORT_CHAINOUT_SAT_IS_OVERFLOW
String
No
Specifies port usage. Values are
PORT_UNUSED
and
PORT_USED
.
When the value is set to
PORT_
USED
, output pin
chainout_sat_
overflow
is added. If omitted,
the default value is
PORT_UNUSED
.
SCANOUTA_REGISTER
String
No
Specifies the clock source for the
scanouta
data bus registers.
Values are
UNREGISTERED
,
CLOCK0
,
CLOCK1
,
CLOCK2
, and
CLOCK3
. If omitted, the default
value is
UNREGISTERED
.
SCANOUTA_ACLR
String
No
Specifies the asynchronous clear
source for the
scanouta
data bus
registers. Values are
NONE
,
ACLR0
,
ACLR1
,
ACLR2
, and
ACLR3
. If
omitted and
SCANOUTA_REGISTER
is used, the default value is
ACLR3
.
CHAINOUT_REGISTER
String
No

chainout mode result register.
This is an additional stage after
the second adder. Values are
UNREGISTERED
,
CLOCK0
,
CLOCK1
,
CLOCK2
, and
CLOCK3
. If omitted,
the default value is
CLOCK0
.
CHAINOUT_ACLR
String
No
Specifies the asynchronous clear
for the chainout mode result
register. This is an additional
stage after the second adder.
Values are
NONE
,
ACLR0
,
ACLR1
,
ACLR2
, and
ACLR3
. If omitted and
CHAINOUT_REGISTER
is used, the
default value is
ACLR3
.
