Internal Error: Sub-system: SGN, File: /quartus/synth/sgn/sgn_hier_connector.cpp, Line: 6144

Description

Due to a problem in the Quartus® II software version 13.1 and earlier, you may see this internal error if your SystemVerilog HDL design uses an unpacked array.

Resolution

To work around this problem, do not use an unpacked array or replace the unpacked array with a packed one.

This problem is scheduled to be fixed in a future release of the Quartus II software.
