Two Triangular Eye Mask Definitions for VIH and VIL
?
DDR2 mask (for nominal VDDQ = 1.8V and VREF = 0.9V):
-
-

-
VIH(ac)-min = VREF + 200 mV = 1.1V
VIH(dc)-min = VREF + 125 mV = 1.025V
VIL(ac)-max = VREF – 200 mV = 0.7V
VIL(dc)-max = VREF – 125 mV = 0.775V
?
QDRII mask (for nominal values of VDDQ = 1.8V and VREF = 0.9V):
-
-
-
-
VIH(ac)-min = VREF + 200 mV = 1.1V
VIH(dc)-min = VREF + 100 mV = 1.0V
VIL(ac)-max = VREF – 200 mV = 0.7V
VIL(dc)-max = VREF – 100 mV = 0.8V
Signal Integrity Correlation Results
This section presents SI results for each of the six chosen memory signals on the ML561
board. The following information is presented for each memory signal:
?
?
?
?
A post-layout IBIS schematics of the signal under test
A description of the major circuit elements (1) of this signal
A summary of four SI results: hardware measurement, correlation simulation, slow-
weak corner driver simulation extrapolation, and fast-strong corner driver simulation
extrapolation
A set of eight figures showing eye and waveform scope shots for each of the four SI
results mentioned in the bulleted list in the previous section
For an explanation of the different terms used to present these results, refer to
“Terminology,” page 9 for some definitions and routing terminologies.
1. With regard to transmission line impedance, Table 3-19 in the “Board Design Considerations” section lists
controlled impedance values of all routing layers. The design goal for the ML561 board is to keep the
characteristic impedance for all routing layers as close to 50 Ω as possible. Manufacturing tolerance is usually
±10%. The characteristic impedance of DIMM PCB is derived from the Micron DIMM layout file.
