Description
Data pattern received on the Write Calibration stage MUX on rising
edge 0.
Data pattern received on the Write Calibration stage MUX on falling
edge 0.
Data pattern received on the Write Calibration stage MUX on rising
edge 1.
Data pattern received on the Write Calibration stage MUX on falling
edge 1.
Data pattern received on the Write Calibration stage MUX on rising
edge 2.
Data pattern received on the Write Calibration stage MUX on falling
edge 2.
Data pattern received on the Write Calibration stage MUX on rising
edge 3.
Data pattern received on the Write Calibration stage MUX on falling
edge 3.
Asserts when the pattern detected is one CK clock cycle early and a
match is found during Write Calibration.
Asserts when the pattern detected is two CK clock cycle early and a
match is found during Write Calibration.
Asserts when the valid pattern is detected on the data and is found to
match with the expected pattern sent during Write Calibration sanity
check.
Tap values set at the end of PRBS Read Leveling stage.
Tap value when the first edge is found during PRBS Read Leveling
stage calibration.
Tap value when the second edge is found during PRBS Read Leveling
stage calibration.
OCLKDELAY center calibration completing indicator.
Final stage 3 tap values for all the bytes in the interface. Bits[5:0] for
byte 0 and Bits[11:6] for byte 1.
Stage 3 tap value during calibration for each group.
VIO Signals (Control)
Currently Unused
Input to select DQS byte for which the ILA displays the tap counts of
PHASER_OUT. For example, set to 4'b0000 to view the results on
DQS[0].
