You can use the set_input_delay and set_output_delay constraints without specifying the related clock. The Vivado Design Suite timing engine will analyze the design and associate each port with all the sampling clocks automatically. Then by reporting timing on the I/O paths, you can see how the tool constrained each I/O port. This is convenient for quickly constraining a design, but this type of generic constraints can become a problem if they are too generic and do not model the hardware reality accurately.
