<p></p> <p><b>New page</b></p><div>{{Other|Oasis (disambiguation)}}<br /> SEMI P39 - '''Open Artwork System Interchange Standard''' (OASIS) is a specification for hierarchical [[integrated circuit]] [[integrated circuit layout|mask layout]] data format for interchange between [[Electronic Design Automation|EDA]] software, [[IC mask]] writing tools and [[mask inspection]] tools. <br /> <br /> The name OASIS is a trademark of the Semiconductor Equipment and Materials Institute ([http://www.semi.org SEMI]). It was developed by a consortium of [[Electronic Design Automation|EDA]] industry companies via SEMI for the [[microelectronics]]/[[Fabrication (semiconductor)|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.<br /> <br /> Like GDSII, OASIS is a hardware- and software-independent [[binary data]] format.<br /> <br /> It delivers the following improvements over GDSII:<br /> *An average of 10-50 times smaller file sizes<br /> *Support of 64-bit arithmetics<br /> *Unlimited design layers<br /> *Richer data format for exchange of information between design and manufacturing stages.<br /> <br /> The sourceforge page for &quot;layout&quot; contains a list of various layout viewers, some of which also read oasis [http://layout.sourceforge.net/links/index.html].<br /> <br /> ==Links==<br /> * [http://www.wrcad.com/oasis/oasis-3626-042303-draft.pdf OASIS specifications]</div>
