摘要： A technique for effectively attenuating EMI noise, which is generated from the electric power system of semiconductor devices, is described. In accordance with the technique, a power supply netlist with an additional electric current source(s) is generated by adding block power supply current waveform data, as extracted from test vector data and a block netlist, to the power supply netlist as extracted from the layout data of the circuit under analysis. A circuit simulation of the power supply netlist with an additional electric current source(s) is then performed in order to calculate power supply current/voltage waveform data. Furthermore, current/voltage spectral data is calculated by the Fourier transformation of the power supply current/voltage waveform data followed by displaying the current/voltage spectral data as the result of the Fourier transformation.

摘要： The speed increasing and accumulating conveyor chain of the present invention can convey a conveyed object faster than the running speed of the chain, and keep the conveyed object stopped while continuously running the chain itself. The load roller with a larger diameter and the running roller with a smaller diameter are coaxially and rotatably mounted on the connecting pin, which is secured to the link plate, respectively. The frictional material is mounted on the load surface of the load roller, wherein the frictional material provides the load surface of the load roller with a larger frictional force than that of rotatable surface between the load roller and the running roller.

摘要： There is provided a method for analyzing a jitter of a clock flowing in a clock path inside a semiconductor integrated circuit. Elements, which belong to any clock domains except for a selected clock domain among operation scenario information, are brought into a halting state, to create a domain operation scenario. Using the domain operation scenario, a power-supply noise analysis is performed on a clock used in the selected clock domain for a period of one to several cycles, to obtain a domain power-supply noise waveform. The obtained waveform is repeatedly connected, to create a cyclic waveform. Part of the cyclic waveform is halted, to obtain a processed domain power-supply noise waveform. The processed domain power-supply noise waveform obtained with respect to each clock domain is superimposed, to create a power-supply noise waveform. Based on the created waveform, a jitter of the clock flowing in the clock path is calculated.
