ID:15456 Port <name> of DSP block output WYSIWYG primitive "<name>" is connected, but the port cannot be connected without the rounding width value of <number> when using symmetric saturation in <name> mode

CAUSE: The specified port of the specified DSP block output WYSIWYG primitive is using symmetric saturation, but the port has an illegal rounding width. Symmetric saturation using the specified port in the specified mode requires the indicated rounding width value. Data using partial-width symmetric saturation is not allowed to propagate to internal adders.

ACTION: Make sure the ROUND_WIDTH parameter is set to the specified value for the specified WYSIWYG DSP block output, set the SATURATE_MODE parameter to ASYMMETRIC, or disconnect the specified port. If rounding is used, disable it.
