OpenAccess Coalition: Goals and Status Sumit DasGupta VP of Technology Silicon Integration Initiative (Si2) Austin, TX 1/13/2019

OpenAccess Coalition (OAC) Structure and Process Outline OpenAccess Goals OpenAccess Coalition (OAC) Structure and Process OAC Participation OpenAccess Technology OpenAccess Status 1/13/2019

OpenAccess Goals Provide an IC design tool infrastructure that yields Integrated systems rather than sequential flows Choice of design tools and provider Technology transfer of innovative research Collaborative design capability for ICs Promote an open standard for IC design data access Gain adoption of the standard within the EDA industry and university research programs 1/13/2019

EDA Interoperability Genealogy Design to Manufacturing Data Sharing Process level integration Multi-vendor integrated systems 2002 Open Data API Single vendor integrated systems Proprietary Data APIs Loosely coupled systems Open File Formats Tool-Data Binding Proprietary File Formats 1/13/2019

Openness Defined... Accessible by all parties: Anyone can use, change, embed, or redistribute according to clearly established terms Reasonable cost: Established prices (if any) are based on service value and do not present an undue barrier to any company, regardless of size Managed migration by stakeholders: Controlled evolution of the technology by an elected Change Team 1/13/2019

OpenAccess Coalition Coalition members have specific rights and responsibilities Share in funding Operate to open, unbiased decision-making policy Abide by OpenAccess Participation agreement terms, and joint funding for development and facilitation Guide future of API and Reference Code Elect Change Team to manage revisions Coalition member benefits Early access to planned/future releases of reference database code Participate in Change Team Set direction and vote on development priorities All things equal, higher priority for member requests Discounted training, support and access to Si2 1/13/2019

OpenAccess Change Team Responsibilities Approving body for API & Reference DB changes Specifies changes to code integrator Caretakers for OA Technical Roadmap Makeup 12 annually-elected Coalition company representatives 1 representative per company, 1 vote per company Max of 5 EDA companies (4 plus Cadence) Chaired by 2 architects who must be CT members (Cadence and 1 elected non- EDA company) Approval of change requires 9 “Yes” votes 1/13/2019

OpenAccess Community Any person/enterprise can download OpenAccess package Click-through Internal Use License Free access to API Free access to reference database binaries for Internal Use Signed Distribution License Free access to reference database source code for Internal Use Royalty-free distribution rights for OA reference database binaries with derivative works Rights to fix bugs (cannot alter API syntax, semantics or behavior) and distribute corrected binaries to customers 1/13/2019

Si2 Role Manages licensing of OpenAccess packages Facilitates and supports the OpenAccess Coalition Facilitate, assist and participate in DWGs and activities Oversee the Change Team Puts in place a program to resolve: Level-1 support for critical bug reports against standard package Resolve interoperability issues Assure compliance of delivered code to the specifications Coordinates with other standards organizations 1/13/2019

OpenAccess Technology OA features: Standard information model for IC design data Standard C++ interface (API) to access and manipulate data Reference commercial-grade database compliant with API Development support aids OA provides: Greater design productivity Standard Model & API provide for choice & tighter design flows Reduced development and support cost Reference DB provides solution for IC designers and EDA developers right out of the box Better interoperability Reference Database provides “golden behavior” for development & test, & for interoperability issue resolution 1/13/2019

Open Access Deliverables The Standard The Reference Implementation Information Model (Graphical) Runtime Memory Data Model (C++ Headers) API Implementation ( Solaris / HP-UX, C++ Binding ) API Specification (C++ Binding) The OpenAccess Standard The standard is the API, which is defined by several documents Information model: describes objects, attributes for each, and relationships for the design data model API Language Reference Manual: defines the function, syntax and semantics of each function (Method) within the API Header files: machine sensible description of the APIs and standard structures and enums Test cases: covering nearly 100% of the API functionality explicitly define the API’s behavior Freely available to anyone Ultimate goal is to gain IEEE accreditation as an industry standard The OpenAccess Reference Database Fully supports the API Production quality Freely available to all Available in binary and source form Royality-free redistribution rights for binaries Persistent Store Application(s) 1/13/2019
