I had not realized that there are two versions of the compiler. Even on the Altera FIR webpage ("FIR Compiler II / FIR Compiler MegaCore Function") it is not clear at all how the 2 versions coexist and differ. To which version does the document "fircompiler_ug.pdf" refer to?

Here is what it says in the MegaCore documentation bit:

- Core Version: v9.1 Build 222

- Release Date: November, 2009

- Ordering Code(s): IP-FIR

- Product ID(s): 0012

And I can't find any "implementation options" tab, so I guess it's bad luck for me: I think it's FIR Compiler I that I have a license for.

ThePancake, I will try and instantiate the filter twice and see how it optimizes.
