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.
Active-Low Clear: Active-Low Preset: Active-High Aload: Active-High Clock Enable: Active-High Clock: Power-up State: D_in: Register Reduces To:
GND             GND
VCC GND           VCC
  GND           !Clear
VCC VCC VCC         Adata
VCC VCC GND GND       Power-up state
VCC VCC GND   VCC or GND     Power-up state
  VCC GND   VCC or GND Low   GND
VCC   GND   VCC or GND High   VCC
  VCC GND GND   Low   GND
VCC   GND GND   High   VCC
  VCC GND     Low GND GND
VCC   GND     High VCC VCC

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.
