Consider 64 flip-flops (clock sinks) laid out in an 8x8 grid, each grid line being 2,500 lambda long in a 0.25 micron technology.
1. Design a zero-skew H-Tree in 3 layers, with buffers inserted in every layer, and each buffer feeding 4 child nodes (which may be other buffers, or clock sink flip-flops). Draw the H-Tree on the grid, indicating the locations of all the buffers, and the distances in microns between the buffers and their child nodes.
