Why doesn't the Reverse Serial Loopback (RSL) feature work on Arria V GX devices in Quartus II Software versions 12.1sp1 and earlier?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT

Description

The Reverse Serial Loopback (RSL) feature does not work on Arria® V GX devices due to a bug in the Quartus® II Software versions 12.1sp1 and earlier.

For RSL Pre-CDR, The Tx signal will be steady state.
For RSL Post-CDR, The Tx signal will exhibit high jitter.
