Abstract

With the ever increasing layout data size due to finer geometries and resolution enhancement techniques such as OPC and PSM, handling several tens of gigabytes of GDSII data is becoming very difficult. While new efficient OASIS format is being proposed to replace it, GDSII is here to stay for next several years. This paper discusses two approaches by which the GDSII data can be handled effectively. Reversible compression will be able to produce original GDSII file bit-by-bit and can produce compression of around 20 times. Irreversible compression can produce functionally equivalent GDSII after decompression.
