Title
Why does fitting error occur for Triple Speed Ethernet IP MegaCore in Cyclone IV GX device?
Description
It is due to the reason that Triple Speed Ethernet’s transceiver reset sequence logic is clocked by reference clock and Cyclone® IV GX dedicated reference clock for transceiver cannot be routed to global clock network.
The following patch provides a solution to ensure no fitting error in CIV GX family devices due to global clock network limitation.
