Question about licenses in megawizard

Hello,

I have got simple question regarding licenses in megawizard.

I am just starting with quartus software (and with the fpga as well) and when it comes to megawizard I am a bit confused.

How can I check if I can use specific megafunction for free?

I used ALTGX and I think this function has no time or any other restrictions. The same with some internal RAM functions.

But then I used some ethernet functions and I am pretty sure it has restrictions.

Is there some simple way to check, if I can use it for free or not? I mean before compilation.

I will be really grateful fore some advices.

best regards,

Tomas
