Modelsim and sqrt function

[Altera_Forum]

Dear Sir 

 I want to simulation with modelsim. I used megafunction sqrt, when I compile it's ok but when I run it, it will show the component "sqrt" are not bound. How can I fix it now?   Thank in advance

make sure you have the lpm and altera_mf libraries mapped in modelsim.

Sorry. Because I saw a lot of file (altea_mf.vhd, altera_mf_87.vhd and altera_mf_component.vhd) Three of them also have sqrt function. I don't know which one should be used.

you need the whole library, not just one or two files.
