What is Clock skew?

Latest Updated:08/01/2005

Question:

What is Clock skew?

Answer:

When multiple circuits are synchronized with a clock, a clock delay is generated and the setup time and hold time cannot be satisfied if there is a critical path that extends routing of the clock line or a gate clock with a logic gate installed on the clock line.
Consequently, the clock cannot sample data in the correct timing. This phenomenon is called clock skew.
