Is there a difference between Direct Compensation mode (as defined in the Altera PLL megafunction) versus No Compensation mode (as defined in the ALTPLL megafunction)?

Description

No, there is no difference between these modes. Direct Compensation mode (as defined in the Altera® PLL megafunction) is equivalent to No Compensation mode (as defined  in the ALTPLL megafunction). In these modes, the PLL does not compensate for any clock networks.
