New ContributorIs "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...

Super ContributorCan you check does your ddio and non ddio register is inside the IO?
Sometimes, quartus will not automatic put those register to the IO that would cause you to have a slower speed.
If the register is inside the IO, means your analysis is correct.
In arria 10, for speed that more than 200Mhz for DDIO. We would suggest customer to use phylite. But not for Cyclone 10LP.
