Spartan-6 GTP - If I am using only one PLL, can I tie the power supply of the second PLL to GND?

For the Spartan-6 GTP, if I am using only one PLL, can the power supply of the second PLL be tied to GND?

If I am not using transmitter or receiver of LANE1 (vice versa for LANE0) can the power supply of PLL1 (vice versa for PLL0) be tied to GND?

No. Both PLL power supplies (MGTAVCCPLL0 & MGTAVCCPLL1) must be powered if any lanes in the GTP Dual are being used.
