ID:14130 Reduced register "<name>" with stuck <name> port to stuck value <number>
CAUSE: Analysis & Synthesis reduced the specified register to VCC, GND, or a wire because it reduced the inputs to the register to one of the following combinations, in descending order of priority. You may have specified this condition in the design file, or the condition may be a result of logic synthesis.

ACTION: If you intended the register to behave in this manner, no action is required. Otherwise, check the design file for errors and make sure the project's logic does not reduce to any of these combinations.
Note: Analysis & Synthesis reduces JK, SR, and T registers to D registers during logic synthesis.
