A global optimization method to synthesize and balance the clock systems in a multimode, multi-corner, and multi-domain design environment is described. The method builds a graph representation for a clock network. The method determines an optimal clock network balancing solution for the clock network by applying linear programming to the graph. To apply linear programming to the graph, the method generates a set of constraints for the graph and determines a proper insertion delay for each edge of the graph by solving for a minimal skew based on the set of constraints. The method implements the optimal clock network balancing solution.
