Description

INPUT_SOURCE_A0 String No Specifies the data source to the

first multiplier. Values are DATAA

and SCANA. If this parameter is set

to DATAA, the adder uses the

values from the dataa[] port. If

this parameter is set to SCANA, the

adder uses values from the scan

chain. If omitted, the default

value is DATAA. For Stratix II

devices, a value of VARIABLE is

available for the adder to perform

rounding and saturation on the

data source before feeding the

result to the multiplier.

INPUT_SOURCE_A1

String No Specifies the data source to the

second multiplier. Values are

DATAA and SCANA. If this

parameter is set to DATAA, the

adder uses the values from the

dataa[] port. If this parameter is

set to SCANA, the adder uses

values from the scan chain. If

omitted, the default value is

DATAA. For Stratix II devices, a

value of VARIABLE is available for

the adder to perform rounding

and saturation on the data source

before feeding the result to the

multiplier.

INPUT_SOURCE_A2

String No Specifies the data source to the

third multiplier. Values are DATAA

and SCANA. If this parameter is set

to DATAA, the adder uses the

values from the dataa[] port. If

this parameter is set to SCANA, the

adder uses values from the scan

chain. If omitted, the default

value is DATAA. For Stratix II

devices, a value of VARIABLE is

available for the adder to perform

rounding and saturation on the

data source before feeding the

result to the multiplier.
