A system and method for clock optimization to achieve timing signoff in an electronic circuit and an EDA tool that embodies the system or the method. In one embodiment, the system includes: (1) a clock cell identifier/sorter configured to identify at least some clock cells in a clock network associated with an electronic circuit design and sort the cells according to breadth, (2) a slack analyzer associated with the clock cell identifier/sorter and configured to identify flops that are downstream of the cells and determine a worst setup and hold timing slack thereof and (3) a clock cell delay adjuster associated with the slack analyzer and configured to adjust delays of the cells subject to the worst setup and hold timing slack.
