摘要： A system, method, and apparatus for local demand response between alternative-energy power-generators, traditional controlled-energy power-generators, and power-consuming loads coupled to a DC bus are disclosed. As a DC bus operating voltage fluctuates between a minimum bus operating voltage to a maximum bus operating voltage, it triggers different power-generators and different power-consumers each having staggered control voltage ranges that enable them to come on-line or go off-line, depending on the bus operating voltage, thereby providing distributed, autonomous and self-regulating demand response performance. Loads vary from opportunistic loads at high alternative-energy generation scenarios, to necessary loads powered by backup or traditional power-generators for low alternative-energy generation scenarios. Safety limits are provided with voltage limits and foldback limits.

摘要： According to various techniques of the present invention, probability models for circuit simulation are generated as linear, piecewise linear, nonlinear, and/or continuous probability waveforms. These waveforms represent probability values for logic levels over some period of time. Probability models are defined according to characteristics of the electronic components being modeled, so as to capture variability in characteristics and performance of logic circuits and their components. The probability waveforms of the present invention can be used to predict circuit component behavior resulting from state changes; a range in response time can be indicated by a probability waveform indicating the probability that the response has taken place at a given time after an input state change. Construction of a probability model for a circuit with interconnected electronic components allows timing problems resulting from variability in component performance to be identified.

摘要： A system and method for slack determination in a logic integrated circuit. A launch pulse is input to a circular delay loop circuit. The leading edge of the launch pulse causes a pulse to circulate around the circular delay loop. The number of passes made through the loop by the circulating pulse is counted by a latch/counter circuit. A sample pulse is input to the latch/counter circuit to latch the number of pulse circulations at the leading edge of the sample pulse. The pulse circulation count provides delay information in the circuit that may subsequently be used to adjust a supply voltage in the integrated circuit.
