Is "Cyclone 10 LP" slower than "Cyclone IV E" ?

I tested according to the same source code (VHDL) shown below. The reported delay was almost the same... but "Cyclone 10 LP" gave the following timing error @300MHz clock. Is my setting incomplete...

Yes, your analysis is correct. This is also the reason why cyclone 10 E does not have emif to be instantiated. In your case, you will have to use cyclone 10 Gx and use phylite or altdq_dqs for it.
