Why don't I see any difference in the transceiver Quartus II Power Play Power Analyzer results when I enable the EyeQ feature on Stratix V GX/T and Arria V GZ devices?

Environment

  • Stratix® V GT FPGA
  • Stratix® V GX FPGA
  • Arria® V GZ FPGA
  • Stratix® V GS FPGA
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

Due to a limitation of the Quartus® II software version 13.0sp1 and earlier, the Power Play Power Analyzer tool will not show any difference in the transceiver power results when you enable the EyeQ feature on Stratix® V GX/T and Arria® V GZ devices.

Enabling EyeQ in the transceiver reconfiguration controller MegaWizard™ will only enable the EyeQ register space but will not switch on the EyeQ feature. The EyeQ blocks are switched on via user-control of the reconfiguration controller management interface at run-time. The Power Play Power Analyser will calculate the EyeQ power based on the default run-time configuration which is "OFF".

Resolution

This limitation will be fixed in a future version of the Quartus II Power Play Power Analyzer.
