Abstract:
A method, comprising:evaluating a power grid at a first time to identify a first set of noisy nodes; inserting a decoupling capacitor of a predetermined size at each of the noisy nodes in the first set of noisy nodes; evaluating the power grid at a second time to identify a second set of noisy nodes; incrementing the size of the decoupling capacitor at each noisy node in the second set of noisy nodes; and after incrementing the size of the decoupling capacitors and there are no more noisy nodes, decrementing the size of the decoupling capacitor at each previously identified noisy node by a predetermined capacitor decrement while maintaining noise level at each previously identified noisy node within corresponding predetermined maximum voltage threshold and predetermined minimum voltage threshold.
