Depending on the value you set for reconfig_mode_sel[3:0], the AEQ has three
modes of operation:
■

For more information about the AEQ port connections and various waveforms in all
the above modes, refer to the
EyeQ
The EyeQ hardware is available in Stratix IV GX and GT transceivers to analyze the
receiver data recovery path, including receiver gain, clock jitter and noise level. You
can use EyeQ to monitor the width of the incoming data eye and assess the quality of
the incoming signal.
Continuous mode—This feature is not supported.
One-time mode—The AEQ finds a stable setting of the receiver equalizer and
locks that value. After it is locked, the equalizer values are no longer changed. This
mode is available in one channel or all channels of the receiver. The
reconfig_mode_sel[3:0] = 1001 in this mode.
Powerdown mode—This feature is not supported.
