The present invention is generally directed to a system and method for identifying a storage node that is susceptible to charge sharing by another node. In accordance with one aspect of the invention, a method identifies storage nodes susceptible to charge sharing by first identifying, from a netlist, a storage node. For a given storage node, the method determines whether any pass FET devices are being driven by the storage node. For any such pass FET devices, the method retrieves a capacitance value for both sides of the pass FET devices being driven by the storage node. Specifically, a first capacitance value is retrieved for the storage node side of each pass FET device, and a second capacitance value is retrieved for a node on the opposite side of each pass FET device. Then the method calculates a ratio between the first and second capacitance values for each pass FET device being driven by the storage node. Finally, the method compares this ratio to a predetermined value, and generates a warning message if the ratio is greater than the predetermined value No.
