Critical Warning (169244): Total number of single-ended output or bi-directional pins in bank have exceeded the recommended amount in a bank where dedicated LVDS, RSDS, or mini-LVDS outputs exists.

Description

This warning will be generated for designs using Cyclone® V devices in the Quartus® II software version 13.0sp1 when using differential and single-ended I/O standards in the same I/O bank.  However, this warning may also be generated by mistake for banks that only contain single-ended I/O pins.

Resolution

The warning can be ignored if there are no LVDS, RSDS, or mini-LVDS signals in banks containing only single-ended I/O standards.

The critical warning is scheduled to be fixed in Quartus® II software version 14.1 so that it is only generated in valid cases.
