Unresolved module

Hi All,

1. I created a new custom megafunction variation ALTPLL and created a Verilog HDL file (e.g. ALPLL0.v and ALPLL0_0002.v).

2. I tried to compile the Verilog HDL file using VCS.

3. I encountered an error regarding Unresolved module pointing to altera_pll.v inside ALPLL0_0002.v.

Question: Do I still need to add a path to resolve this? Or I' am missing something during creation of new custom megafunction variation?

BTW I'am using Arria V

Many Thanks in advance,
