A hierarchical clock distribution system includes a global clock grid that distributes a clock signal to a plurality of regional clock grids. Each of the regional clock grids then distributes the signal to a plurality of corresponding loads. The regional clock grids utilize salphasic clocking techniques to distribute the clock signal to the corresponding loads. The global grid achieves low skew based on the periodicity of the clock signal, rather than the dominance of a standing wave. The electrical distance to termination within the regional clock grids is preferably kept low to avoid the occurrence of phase change regions on the regional grids. In one approach, the regional grids are each driven at multiple points in a symmetrical fashion to reduce the electrical distance to termination.
