In the Quartus® II software version 13.0sp1, you may see this internal error when running the PowerPlay Power Analyzer if a transceiver receiver channel uses either the LVDS or the Differential LVPECL I/O standard, targeting Cyclone® V, Arria® V, and Stratix® V devices.
The power analyzer misidentifies transceiver channels as general-purpose I/O (GPIO) pins, but the GPIO pins do not have data on HSSI-specific termination settings.
A patch is available to fix this for the Quartus® II software version 13.0sp1.
This patch allows the power analyzer to correctly identify transceiver channels and retrieve the appropriate data for its calculations.
This problem is fixed in Intel® Quartus® 13.1.
