How to find a IP is free or requires license ?

[Altera_Forum]

I'm looking to use LVDS Serdes IP and just checking about it to see its free or requires license. The user guide does not provide clear information It states a generic statement. 

 Incase of other vendors, there would a lock logo next to that IP in the IP catalog. Is there anything of that sort is available with altera.  Did i miss to see anything,  -- Thanks Rajesh

Hi sstrell, 

Thanks for the reply. My question was "I see a IP in the Quartus IP catalog. How do i know that it requires a license for production. " What are the different types of evaluation for IPs available. Atleast i know that for NIOS2, it time limited.
