ZWL Zero Wire Load
This is a Zero Path(ZP), meaning that the required time at endpoint is less than the arrival time at the start time, so there is not enough time for the signal to propagate to the endpoint.
Zero Path violations are independent of the physical layout of the circuit. In other words, it is impossible for the design to meet timing on this path.
