Description Due to a problem in the Quartus® II software versions 12.1 and earlier, the Arria® II GZ XAUI Hard IP simulation model instantiates Stratix® IV atoms. Although these atoms are functionally equivalent to the the Arria II GZ atoms, the msim_setup.tcl script generated by the MegaWizard™ Plug-In Manager does not include the Stratix IV simulation libraries. Due to this problem, your design may fail during elaboration when simulating using Mentor Graphics ModelSim software.
Resolution To work around this problem, edit your msim_setup.tcl script to point to the Stratix IV libraries. See Altera Simulation Models in Quartus II Help for a list of libraries.
