ID:12123 Cannot remap LVDS PLL "<name>" because the VCO_MULTIPLY_BY value is 0 which is invalid for such a PLL
CAUSE: You changed the target device family for a design, and compiled the design. The design instantiated a PLL that feeds an LVDS receiver and/or LVDS transmitter for the old target device family. However, the VCO_MULTIPLY_BY
value for this PLL is 0 which is invalid. As a result, the Quartus Prime software is unable to remap this PLL from the old target device family to the new target device family.
ACTION:
- Ensure that the values for
VCO_MULTIPLY_BY
andVCO_DIVIDE_BY
are valid for LVDS mode. - Use the
altlvds_rx
oraltlvds_tx
megafunction when generating the design that instantiates the PLL.
