CPRI IP Core Variations That Target a Cyclone V GX Device Do Not Achieve Timing Closure - CPRI IP Core Variations That Target a Cyclone V GX Device Do Not Achieve Timing Closure Description CPRI IP core variations that target a Cyclone V GX device fail to achieve timing closure with the default Quartus II Fitter settings. Specifically, they experience hold time violations on the PCS-PLD path. Resolution To achieve better timing closure results, perform one of the following actions: Add set_min_delay assignments to overconstrain timing. Try different Quartus II Fitter seeds. This issue will be fixed in a future version of the CPRI MegaCore function.
