Direction
Specify the bus number format that you want to use. Inferred means
that the format is automatically set by the format of the connected
signal.
Specify the number of bits to the left of the binary point.
Specify the number of bits to the right of the binary point. This option
applies only to signed fractional formats.
Specify the elements that you want pipelined. The clock enable and
asynchronous clear ports are available only if the block is registered.
Turn on to use the clock enable input (ena).
Turn on to use the asynchronous clear input (aclr).
If you target devices that support DSP blocks, turn on to implement the
functionality in DSP blocks instead of logic elements.
Preliminary
Complex operand a.
Complex operand b.
Optional clock enable.
Optional asynchronous clear.
