A method of creating a black box timing model for a digital circuit. The digital circuit is characterized by a block model having at least one input and at least one output. The method determines a delay statement for the output of the block model. The method also determines an input set-up constraint for the input of the block model. The input set-up constraint is based upon the delay statement. The model is then used with a static timing analyzer to accurately model a flow-through circuit.

Black box timing model for latch-based systems

A system and method for automatically selecting decoupling capacitors for an electronic device. The system determines a localized drive strength for each component in the electronic device. Based on a summation of drive strengths for components in a given area of the electronic device, the system determines whether a decoupling capacitor is necessary to provide local power bus stability.
