Section II. DDR3 SDRAM Controller with ALTMEMPHY IP User Guide
The reference clock input to the PHY PLL.
Active-low global reset for PLL and all logic in the
PHY. A level set reset signal, which causes a
complete reset of the whole system. The PLL may
maintain some state information.
Edge detect reset input intended for SOPC Builder
use or to be controlled by other system reset logic.
Causes a complete reset of PHY, but not the PLL
used in the PHY.
Directly connected to the locked output of the PLL
and is intended for optional use either by automated
tools such as SOPC Builder or could be manually
ANDed with any other system-level signals and
combined with any edge detect logic as required
and then fed back to the global_reset_n input.
Reset request output that indicates when the PLL
outputs are not locked. Use this as a reset request
input to any system-level reset controller you may
have. This signal is always low while the PLL is
locking (but not locked), and so any reset logic
using it is advised to detect a reset request on a
falling-edge rather than by level detection.
Half-rate clock supplied to controller and system
logic. The same signal as the non-AFI phy_clk.
Reset output on ctl_clk clock domain.
In half-rate designs, a copy of the phy_clk_1x
signal that you can use in other parts of your
design, same as phy_clk port.
In full-rate designs, a copy of the mem_clk_2x
signal that you can use in other parts of your
design.
The signal sent from the DIMM to the PHY to
indicate that a parity error has occured for a
particular cycle.
