Description
SYSTOLIC_DELAY1
String
No
Specifies the clock source for
the systolic register inputs of
the first multiplier. Values are
UNREGISTERED
,
CLOCK0
,
CLOCK1
, and
CLOCK2
. The
value must be set similar to
the value of
OUTPUT_
REGISTER
or set as
UNREGIS-
TERED
.
SYSTOLIC_DELAY3
String
No
Specifies the clock source for
the systolic register inputs of
the third multiplier. Values
are
UNREGISTERED
,
CLOCK0
,
CLOCK1
, and
CLOCK2
. The
value must be set similar to
the value of
OUTPUT_
REGISTER
or set as
UNREGIS-
TERED
.
SYSTOLIC_ACLR1
String
No
Specifies the asynchronous
clear source for the systolic
register inputs of the first
multiplier. Values are
NONE
,
ACLR0
, and
ACLR1
. If omitted
and the corresponding
SYSTOLIC_DELAY[]
is used,
the default value is
ACLR0
.
The value must be set similar
to the value of
OUTPUT_ACLR
.
SYSTOLIC_ACLR3
String
No
Specifies the asynchronous
clear source for the systolic
register inputs of the third
multiplier. Values are
NONE
,
ACLR0
, and
ACLR1
. If omitted
and the corresponding
SYSTOLIC_DELAY[]
is used,
the default value is
ACLR0
.
The value must be set similar
to the value of
OUTPUT_ACLR
.
COEF0_[]
Integer
No
Specifies the coefficient value
[0..7]
for the inputs of the
first multiplier. The number
of coefficient bits must be set
similar to the value of
WIDTH_
COEF
.
