Why doesn’t the Intel® Arria® 10 EMIF Debug Toolkit report the AC Calibration Margin?

Description

There’s no Address/Command (AC) calibration margin reported in the Intel® Arria® 10 EMIF Debug Toolkit if either one of the 2 conditions below occur.

1. Under the Diagnostics tab of the Intel Arria 10 EMIF IP, the "Skip address/command leveling calibration" option is enabled.

2. Under the Memory tab of the Intel Arria 10 EMIF IP, the “Bank group width" parameter is set to 1.

The Address/Command calibration margin is reported if the "Skip address/command leveling calibration" option is disabled and if the “Bank group width" parameter is set to a value greater than 1.
