SoftJin’s OA to OASIS Translator
Bi-Directional OpenAccess to OASIS Translator
Enables direct conversion of design files from the OpenAccess database to OASIS and OASIS back to OpenAccess, without going through any intermediate format
Key Advantages • Cuts down conversion time of OpenAccess to OASIS and vice-versa by half as compared to the conventional approach of going through GDSII • Minimizes storage space during conversion - Direct conversion avoids this data size explosion. • Prevents any loss of information during the conversion process Silicon Integration Initiative Integration Silicon See http://www.softjin.com/html_new/oa_oasis.html for details Innovation Through Collaboration 13 OpenAccessOpenAccess ComponentsComponents

Innovation Through Collaboration 16 OpenAccessOpenAccess Benefits:Benefits: EndEnd--useruser –– DesignDesign
• Single storage per data type, hence no duplication, conflict, confusion
• Significant reduction in data translation, leading to optimized, higher performance flows
Simpler design flows, hence simpler scripts for same complexity of design
Reduces/eliminates performance impact on design flows
• Strong enabler for distributed design teams
Modern integrated database removes headache of managing large, loosely- connected set of files Silicon Integration Initiative Integration Silicon
Innovation Through Collaboration 17 OpenAccessOpenAccess Benefits:Benefits: EndEnd--useruser -- EDAEDA
• Saves investment in proprietary API, data model & database solution
• Enhances interoperability with vendor tools
Reduces/eliminates investment to develop/maintain translators
Plug-and-play access to new tools reduces integration costs
Reduces/eliminates performance impact of translators on design flows
• Allows focus on core competencies, i.e., developing value-added internal tools and customized flows
• Leverages collective knowledge base and contributions of OpenAccess community at reduced cost (~1/N), including academia Silicon Integration Initiative Integration Silicon
Innovation Through Collaboration 18 OpenAccessOpenAccess Benefits:Benefits: EDAEDA CompaniesCompanies
• Large EDA companies:
Easier access to customers ¾ Simpler integration into their flows
Less interfacing effort ¾ Focus on tool development
Easier to integrate tools when purchasing small vendors
• Small EDA companies (start-ups):
Reduces barrier to entry, i.e., quicker “startups”, faster ROI
¾ Focus on tool development, not custom infrastructure
¾ Custom infrastructure often barrier to acceptance
Less interfacing effort
¾ Quickly sell to a larger market Silicon Integration Initiative Integration Silicon
