Megawizard DDR3 Controller with Uniphy : Generation failed

I'm trying to create a DDR3 controller for Cyclone V with Megawizard. A lot of ERRORS appear on the processing window and at last "Generation failed" message.

It´s a basic task, how can it fail?. It's a bug?.

Any idea?.

PD: I can't copy-paste the error messages from the processing window, and I can not find find a file with errors.

    any chance you have your CAS latency set to 11?

    I have the same problem with a Arria V which issues the generation failed error when i choose CAS = 11 all others option are being generated.

    Not CAS latency to 11. My CAS values are 7 and 6.

    I only choose a DDR3 memory model (Micron) from de Megawizard list and I let it fill default vaues.
