Synchronization of data, control and clock inputs in QuartusII

Hey everyone,

i am getting a data(4 Bit), a control(1 Bit) and a clock signal from the Cyclone V pins which are driven by extern sources.

These signals are misaligned and i want to align the control and the data signals to the extern clock signal in my FPGA design.

Are there any Altera/QuartusII provided IP-Cores available to this task? What is the best method to align them?

The deskew isn't static, so timing constrains are probably not the right solution.

I am using Cyclone V and QuartusII 2017.

Every help is very appreciated, thanks in advance.

Best regards

    Add a PLL and choose one of the available clock compensation options.
