SEMI P39 - Open Artwork System Interchange Standard (OASIS) is a specification for hierarchical integrated circuit mask layout data format for interchange between EDA software, IC mask writing tools and mask inspection tools.
The name OASIS is a trademark of the Semiconductor Equipment and Materials Institute (SEMI). It was developed by a consortium of EDA industry companies via SEMI for the microelectronics/fabrication industry as a replacement for the GDSII format, the IC industry de facto standard for IC layout data exchange for more than two decades.
Like GDSII, OASIS is a hardware- and software-independent binary data format.
It delivers the following improvements over GDSII:
- An average of 10-50 times smaller file sizes
- Support of 64-bit arithmetics
- Unlimited design layers
- Richer data format for exchange of information between design and manufacturing stages.
The sourceforge page for "layout" contains a list of various layout viewers, some of which also read oasis [1].
