DDIO Input Speed Cyclone V vs. Cyclone 10GX

When I create a simple DDIO input for both the Cyclone V and Cyclone 10GX parts, the Cyclone V has an Fmax about twice the Cyclone 10GX. Cyclone V, Fmax ~ 400Mhz Cyclone 10GX, Fmax < 200...

Hi Greg,


I am Adzim from Global Application Engineer team will assist you in this issue.


I would like to have your confirmation here regarding to this issue.

The attachments are failed to open due to corrupted file. Can you re-attached it again?


You are using Cyclone 10 GX device and currently observing the fmax is lower than other devices. Which IP that you used for that observation?


Do you have any problem to configure the DDR IP? Do let me know if you have any.


Thanks & Regards,

Adzim

    I am using GPIO Intel FPGA IP. I have made a fresh archive of the project and have attached it. Yes, the Fmax is lower than other devices and I have no problem configuring the IP.

    Thanks,

    Greg
