Quartus

Truncated number -- number cannot be assigned to group of lesser width


CAUSE: In a Text Design File (.tdf), you assigned a number to a group, but the amount of bits needed to represent the number is greater than the size of the group. The Quartus II software removed the MSB and as many adjacent bits as necessary from the number to match the size of the group, and therefore changed the number.
ACTION: Change the size of the group so it contains enough bits for the number.
