Parameter Name Type Required 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.
