I have got timing problems with a ACEX1K30 Design.

Even if you're just starting out learning and not doing a design for actual hardware, it is best to use a modern device family. Some Quartus features are not available for old device families, so you won't be able to do everything you could do for an new real design using a recent (or at least more commonly used) device family.

If I'm just experimenting and not doing something device-specific, I like to choose the smallest device in one of the Cyclone families for quick compile times.
