But you can avoid these IPs almost entirely by using
i) Inference (so you can write behavioural, mostly portable VHDL code)
http://www.altera.co.uk/literature/h...s_qii51007.pdf ii) using the altera_mf library yourself (instantiate the megawizard IPs without using the megawizard). For example, the alsyncram megafunction can be found in quartus help.

I would be happy if this applies to all Altera IP. Recent IP like the Altera_PLL used with Cyclone V and other newer chips doesn't even have a user manual describing the parameters. It works with a minimal number of parameters for basic applications, but if you are attempting to use advanced features like dynamic phase shift, they will be probably ignored without a warning if you don't know some undocumented parameter names and which of them must have non-default values.
