Abstract
Method for automatically analyzing complex electronic circuit designs for generalized types of floating FET gate circuit design errors that encompass both standard floating gate issues and previously difficult-to-find high impedance situations. The invention views electronic circuits as comprising a large number of 'circuit stacks', each stack having a small number of electronic devices between a given power and ground rail within the circuit. The invention uses a computer processor and a recursion algorithm to automatically analyze circuit netlists, determine the different circuit stacks, stack input-output functions, and stack devices, and use an expression algorithm to determine a logical expression of the given stack's input-output function. The invention determines nodes that are connected to various FET gates, and checks if various given FET gates are connected to any DC-pin devices that might produce floating or high-impedance floating input to these FET gates, thus causing that particular FET gate to float.
