Abstract
An integrated circuit includes a first vertical clock bus and a first interface circuit coupled to provide first global clock signals to the first vertical clock bus. The first interface circuit is coupled to a first external terminal of the integrated circuit. The integrated circuit also includes a second vertical clock bus and a second interface circuit coupled to provide second global clock signals to the second vertical clock bus. The second interface circuit is coupled to a second external terminal of the integrated circuit. A third horizontal clock bus is coupled to provide the first and the second global clock signals from the first and the second vertical clock buses to a center region of the integrated circuit.
