ID:15052 LVDS PLL "<name>" was converted to a regular PLL because it does not feed an LVDS receiver or transmitter

CAUSE: The specified LVDS PLL does not feed any LVDS receivers or transmitters. As a result the specified PLL was converted into a regular PLL that does not use features specific to an LVDS PLL.

ACTION: If a regular PLL was intended, then do not use features specific to an LVDS PLL and instead create a regular PLL using the altpll megafunction. Otherwise, make sure the PLL feeds an LVDS receiver or transmitter.
