Why are the VOD, pre-emphasis, and slew rate parameters reported as -1 for Stratix® V, Arria® V, and Cyclone® V FPGA transceiver pins in the Resource Property Editor when using Quartus® II software version 13.0 and 13.0sp1?

Description

Due to a bug in Quartus® II software versions 13.0 and 13.0sp1, VOD, pre-emphasis, and slew rate parameters are incorrectly reported as -1 for Stratix® V, Arria® V, and Cyclone® V FPGA transceiver pins in the Resource Property Editor.

Resolution

You can refer to the fitter results for the assigned VOD, pre-emphasis, and slew rate parameters.

This problem has been resolved in the Quartus II software version 13.1 and onwards.
