332 - Lattice Diamond: Can I have the same logic assigned to different UGROUPs?

Logic is only permitted to be constrained by a UGROUP preference one time. All UGROUP preferences are mutually exclusive. When UGROUP preferences collide the second UGROUP assignment will strip logic from the first assignment. For example:

  • When UGROUP 2 attempts to constrain the placement of logic already being included in UGROUP 1.  The UGROUP 2 preference causes the portion defined in UGROUP 2 to be deleted from UGROUP 1.
  • When UGROUP 2 has exactly the same logic as UGROUP 1, UGROUP 1 is deleted.
