Quartus

WYSIWYG LCELL primitive <name> cannot have improperly connected cascin port


CAUSE: The specified WYSIWYG LCELL primitive has a cascin port that is inverted or connected to VCC, GND, or a pin. However, the cascin port must be driven by the cascout port of another WYSIWYG LCELL primitive. A WYSIWYG LCELL primitive that uses its cascout port must be used in order to send the appropriate signal to the WYSIWYG LCELL primitive.
