ID:287113 Numbers cannot be assigned to nodes

CAUSE: In a Boolean equation in a Text Design File (.tdf), you assigned a number to a single node. Because Analysis & Synthesis always interprets numbers as groups and you cannot assign a group to a node, you cannot assign a number to a node.

ACTION: In the Boolean equation, assign numbers to groups only. If you want to assign 0 and 1 to a node, you can use VCC and GND instead of 0 and 1.
