Abstract

The OASIS format was designed to be a replacement for the GDSII stream format. Previous papers have reported that OASIS files can be 5-20X smaller than comparable GDSII files. This paper examines the storage capabilities of OASIS, as well as other benefits, in more detail. The primary focus of this study is on OASIS integers, deltas, point-lists, and its explicit support for rectangles & squares. We also show how the two OASIS integer types and four delta types can be implemented using a single core procedure.
