With the rapid development of semiconductor technologies and increasingly greater IC scales and design complexity
all the EDA tools become more elaborate with each passing day.To improve the design efficiency with the aid of these tools has become a focus in the IC arena.In this paper
a TCL language-based system framework for the automated environment of IC design flow is introduced and its implementation method detailed.With the framework
IC designers can easily customize various types of automatic IC design flow and shorten their design cycles.
