Development of standard cell libraries using variable driving strength cell layout generation system

摘要

We developed standard cell libraries for three deep submicron processes using VARDS(VARiable Driving Strength). VARDS is improved to consider the design rules dedicated to very deep submicron technologies. VARDS can generate cell layouts for almost all current technologies. Thanks to VARDS, these cell libraries can be developed in short time and they are competitive in performance compared with commercial libraries. These libraries will be distributed to educational institutions by VDEC and used to design LSIs.
