ALTCLKCTRL not being instantiated by Modelsim-Altera

Quartus 14.1 Modelsim-Altera 10.3c

Simple VHDL code using Cyclone V. Instantiates ALTCLKCTRL.

.QIP and .SIP added to project as directed. Synthesizes OK.

Modelsim-Altera error: "Instantiation of 'gclk0_altclkctrl_0' failed"

Name of IP is gclk0. The _altclkctrl_0 is postfixed to my IP name.

Why can't Modelsim-Altera find it?

If Quartus 13.0sp1 is used Modelsim-Altera works OK.

    The ALTCLKCTRL IP should need the cyclone V device library only,eg cyclonev_atoms.vhd, for simulation. Confirm again the right library to be compiled or using native-link to run the setup simulation script. Hope it will work for you.

    As said above, the ALTCLKCTRL IP can be simulated if you add to your ModelSim project, the device library located in /Altera path/quartus/eda/sim_lib/ as xxxx_atoms and xxxx_components (xxxx = your device).

    It worked for me in a STRATIX V Project.

    Since Quartus 13.0sp1 is working, probably you can try with latest 15.0 to check if this is due to version specific issue.
