RLDRAM II Interfaces

In RLDRAM II interfaces, the only PLL phase shift that you can change
using the MegaWizard is for the address/command clock connection
phase shift (see

Figure 3–7

) . You can also change the address/command

clock connection directly in the RTL, and its phase shift using the altpll
MegaWizard.

RLDRAM II interfaces uses two other clocks: system clock and write
clock, which have default phase shifts.
