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

See http://www.softjin.com/html_new/oa_oasis.html for details

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

OpenAccess Benefits: EndOpenAccess Benefits: End--user user –– 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 designReduces/eliminates performance impact on design flows

• Strong enabler for distributed design teamsModern integrated database removes headache of managing large, loosely-connected set of files

OpenAccess Benefits: EndOpenAccess Benefits: End--user user -- EDAEDA

• Saves investment in proprietary API, data model & database solution

• Enhances interoperability with vendor toolsReduces/eliminates investment to develop/maintain translatorsPlug-and-play access to new tools reduces integration costsReduces/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

OpenAccess Benefits: EDA CompaniesOpenAccess Benefits: EDA Companies

• Large EDA companies:Easier access to customers

Simpler integration into their flowsLess interfacing effort

Focus on tool developmentEasier to integrate tools when purchasing small vendors

• Small EDA companies (start-ups):

Reduces barrier to entry, i.e., quicker “startups”, faster ROI

Focus on tool development, not custom infrastructureCustom infrastructure often barrier to acceptance

Less interfacing effort

Quickly sell to a larger market
