lpm functions and hdl

Hi all, So I'm trying to create a (synchronous) 8-bit loadable counter, as below but for some reason this synthesizes to around 28 LE's compared to the altera LPM 11 LE version. Any idea why? ...

The case shows that the synthesis tool is pretty good in optimizing arithmetic code so that functionally equivalent designs usually end up with equal resource usage.

Regarding Trickys comment, I would prefer a more straightforward behavioral description of the up/down counter with fewer always blocks and without the auxiliary q_next.
