摘要： In a preferred embodiment, the invention provides a circuit and method for reducing soft error events in latches. A low-pass filter is placed between the output of a forward inverter and the inputs of a feedback keeper. The first and second outputs of the low-pass filter are connected to first and second inputs respectively of the feedback keeper. The only type of diffusion connected to the first output of the low-pass filter is a P-type diffusion. The only type of diffusion connected to the second output of the low-pass filter is an N-type diffusion. The feedback keeper is connected to an input of the forward inverter.

摘要： Systems and methods are provided that can be utilized to estimate power associated with a circuit design. The estimated power is determined by employing power characterizations to determine power consumption associated with non-conventional circuits in the circuit design. The power characterizations can be determined prior to circuit design timing analysis, stored and utilized during circuit design timing analysis. The power estimates associated with the non-conventional circuits can be added to power estimates associated with the conventional circuits of the circuit design to compute a power associated with the circuit design.
