DDR2 design compilation very long !

Hi,

I'm currently trying to test a DDR2 (MT47H32M16 -25E) on a board but the compilation time is very very long... (more than 4 hours for a block diagram with only one PLL and a DDR2 SDRAM Controller with ALTMEMPHY. I thought the problem was about parameters I changed to have a custom design file for MT47H32M16 -25E but when I select a memory preset I have the same result.

I already made some tests a few months ago on a cyclone IV GX evaluation board and the compilation was during about 10 minutes.

There must be something wrong somewhere, but I have no clue where to look for solving this problem.

If anyone have an idea, please tell me.

Thanks.
