Vivado Timing Analysis - Why is the set_input_delay without clock option ignored?

Description

Why is the set_input_delay command ignored?

I have used the set_input_delay command without the -clock option, but it appears that the command is ignored.

I receive the following warning:

CRITICAL WARNING: [Constraints 18-449] set_input_delay: No clock objects specified for -clock option, set_input_delay without -clock option will constrain the pin/port with a virtual clock.

Solution

The set_input_delay command requires the -clock option.
