Hello people,

@FvM it is why i opened this topic in the Altera's forum. The synthesis output tdf file (AHDL) is generating an initiliaze file (mfi) for the RAM. When I don't initilialize the RAM

signal RAM : RamType;

instead of

signal RAM : RamType := InitRamFromFile("ram_init.txt");

no initiliaze file (mfi) for the RAM is created.

For your information, XST which is the xilinx's synthetiser is working correctly with this manner.

I raise my issue to altera via mysupport.

So wait and see...

Thanks for your help :)
