IRREGULARITIES SIMULATION SYSTEM

摘要

There is provided an irregularities simulation system enabling easy circuit design suppressing performance deterioration attributed to irregularities. An irregularities analysis unit (100) extracts in advance statistical characteristic of irregularities from a plenty of device samples. A model analysis unit (200) checks response to the parameter fluctuation of the circuit simulation. A fitting execution unit (300) combines these information and decides the parameter irregularities distribution so that circuit simulation reproduce the statistical characteristic of the device samples.
