Autolink Setup
This feature provides the following options:
The receiver data checker must be active to determine whether the settings attempted
by the hardware are successful. Therefore, you must connect the transmitter output to
the receiver input through external cable.
If you are evaluating the characteristic of a third party upstream transmitter
connected to the Stratix IV GX receiver, you must supply the appropriate data pattern
as selected in the application, for the data checker to determine the BER for a given
setting.
Autolink Start and Stop
Selecting the start option enables the hardware to perform the operation specified in
Autolink setup. After this setup is complete, the stop field gets highlighted in green
or red. Set the stop field and record the converged settings. The following explains the
color coding of the stop field:
The DataChk Status field also shows whether the hardware is in progress, done
(successful), or no setting (failure) status.
Data Patterns
The application supports PRBS15i, PRBS7, PRBS23, CJTPAT, compliance pattern (only
for specific designs and channels), high frequency, and low frequency patterns. No
synchronization patterns are sent prior to sending the PRBS pattern. Therefore, you
can use a third party receiver to recognize the PRBS/CJTPAT data.
Data verifiers are not available for the high frequency (1010..) and low frequency (5’1s
and 5’0s) patterns.

Description
You can manually change the preemphasis and equalization to observe the
setting that provides an error free link. For more information about
DataChk Status, refer to
When you select this option and the start button, the hardware finds a
preemphasis and equalization setting that meets the bit-error rate (BER) of
10–12.
When you select this option and the start button, the hardware finds an
equalization setting that meets the BER of 10–12.
When you select this option and the start button, the hardware finds the
preemphasis settings (pre tap and 1stpost tap) to obtain an error free link.
Description
the hardware successfully finds the settings that give an error free link.
if the hardware is not able to find the settings, it provides the setting that
yielded the least number of errors.
the hardware is finding the PMA settings.
