Internal Error: Sub-system: FIOMGR, File: /quartus/fitter/fiomgr/fiomgr_io_power_region.cpp, Line: 2460

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

You may see this error in the Quartus® II software for designs targeting Stratix® V and Arria® V devices. This error occurs if your design contains differential signals where both the positive and negative legs (true and complement) have been manually defined and connected in your netlist without using the altiobuf primitive.

Resolution

To avoid this error, do one of the following actions:

  • Define only the positive leg of your differential signal in your netlist. The Quartus II software automatically creates and connects the negative leg for your differential signal.
  • Use the altiobuf primitive to connect both the positive and negative legs of your differential signal. See the related solution below for information about how to use the altiobuf primitive.

This problem is scheduled to be resolved in a future version of the Quartus II Software.
