11. Concluding Remarks
It is remarkable, in these twenty years, personal telecommunications, especially mobile phone, have been widely popular. In
these evolutions, mainstream of electronics parts was radio-frequency integrated circuits, particularly silicon based
radio-frequency integrated circuits. However, silicon based semiconductor devices have involved some of difficulty on theirelectrical characteristics such as high frequency characteristics, conductive substrate, etc. with compare than compound
semiconductor. Moreover, radio-frequency integrated circuits faced more difficulty due to highly integration and coexistencewith digital circuits, and they have been overcome. In above story, modeling and simulation techniques have supported therealization of radio-frequency integrated circuits, and also they will be more advanced in future.
In this workshop, entitled "Simulation technique for design of radio-frequency integrated circuits", there were presentation ofalmost all steps of radio-frequency integrated circuits design, through from device modeling to system design, and wereactive discussions. In concretely, they were "RF modeling of MOSFETs including process variation", "Challenges andSolutions for RFIC Realization", "Methodology for substrate coupling analysis with high frequency accuracy", and"Behavior Model of RF transceivers".
Many attendees had a time of active discussion, and knew importance of simulation techniques, and deeply understood them,in this workshop.

11. Concluding Remarks
It is considered that the simulations are very important scheme in the fabrication of hardware. It is fact that the simulations
are supported by computer technology and software technology. An important thing is both of computer and software are
made by human beings. In recent years, huge scale models can be simulated due to development of computer and software
technology and these synergy effects.
There were five presentations in this session. Three presentations were "Vector super computer technology", "Clustercomputer technology", "GPGPU technology" as computer technology. Two presentations were "Frequency domain analysis
technology" and “Time domain analysis technology" as electromagnetic analysis technology.
All presenters mentioned about view of bright future in these technology. Therefore, unpredictable huge scale simulation will
be realized in ten years by development of computer and software technology and these synergy effects.
