Abstract:
An apparatus for detecting a predischarge node in an integrated circuit, the apparatus comprising:a computer capable of being configured to execute a rules checker program, the rules checker program analyzing information relating to the integrated circuit to determine whether a predischarge node exists in the integrated circuit, wherein when the rules checker program is executed by the computer, the rules checker program evaluates each node in the integrated circuit to determine whether or not each node in the circuit is a predischarge node by analyzing the information relating to the integrated circuit to determine whether or not the node being evaluated is connected to an N field effect transistor and to a P field effect transistor, by determining whether or not the N field effect transistor has a gate terminal which is connected to a clock and has either a drain or a source terminal connected to ground, and by determining whether or not the P field effect transistor has a gate terminal which is not connected to a clock and has drain and source terminals which are not connected to a supply.
