Input <BACTr> is never used. This port will be preserved and left unconnected if it belongs to a top-level block or it belongs to a sub-block and the hierarchy of this sub-block is preserved. Signal <C8MFall> is assigned but never used. This unconnected signal will be trimmed during the optimization process. Input <nBG_IOB> is never used. This port will be preserved and left unconnected if it belongs to a top-level block or it belongs to a sub-block and the hierarchy of this sub-block is preserved. Input <DBG> is never used. This port will be preserved and left unconnected if it belongs to a top-level block or it belongs to a sub-block and the hierarchy of this sub-block is preserved. The value init of the FF/Latch 0 hinder the constant cleaning in the block MCKE. You should achieve better results by setting this init to 1. Node <C8Mr_1> of sequential type is unconnected in block <CNT>. Node <C8Mr_0> of sequential type is unconnected in block <CNT>. The value init of the FF/Latch MCKE hinder the constant cleaning in the block fsb. You should achieve better results by setting this init to 1.
