Hi AdzimZM_Altera​ 

I have used Superior Performance with Maximum Placement Effort performance option and also tried the EMIF document optimize timing method by updating the Placement Effort Multiplier to 2 still same violation is observed.

    I make hps_subsys as a top level, set the hps bridge as virtual pin and compile the design.

    I don't get the timing violation as you see.

    Can you try that from your end?
