ID:11380 Input from node "<name>" to node "<name>" is extended from a number without MSB(s).

CAUSE: You extended (no matter signed or unsigned) a partial number which has already lost its MSB. Normally, extending an non-MSB bit may not be a proper operation.

ACTION: If you want to use a partial number, don't extend it. If you don't want the deficiency, widening this input bus may be helpful. If widening input bus is not helpful, it is likely that the number from the resource node is already deficient.
