Coordination of OpenAccess with other relevant industry programs to assure consistent direction and strategy. Back to Table of Contents

II. Coalition Membership Responsibilities

The OpenAccess Coalition will promote interoperability of EDA application on a standard API in order to enable greater consumer choice of EDA applications. Coalition membership is on a company or organization (i.e. it is possible for a bona fide industry organization such as a not-for-profit industry consortium or university to become a member) basis. Although many employees of a company or organization may participate in Coalition activity, no more than one vote per member (company or bona fide industry organization) is allowed on any decision.

Any company or bona fide industry organization may become a member of the Coalition. However in order to do so, that company or organization must first commit in writing to be an active member of the Coalition by assignment of resources (engineering and financial) to each of the following three (3) areas:

At least one (1) of the following:

  • Develop, port, support, or use for commercial electronics design, a production-level EDA application(s) that relies on the OpenAccess API as the primary access to design data.
  • Develop, port, support, or use for commercial electronics design, a production-level database (including the OpenAccess reference database) that supports the OpenAccess API.
  • [Bona fide organizations only] Organize, coordinate and actively participate in development or research that leads to: significant enhancement to the OpenAccess standard or reference database; or, its adoption and use in areas of the IC supply-chain beyond that of chip design.

Coalition members are not restricted from developing, selling, using or marketing any alternative to the OpenAccess API.

Active Participation

Active participation within the Coalition on matters concerning its operations and promotion of its goals to include: voting on decisions by the Coalition, participating in events or other efforts that promote OpenAccess adoption, assigning personnel to relevant Development Work Groups, and (where permitted) submit reference designs to Si2 that aid in regression testing.

Shared Funding

Execute and abide by the OpenAccess Service Purchase Agreement terms, including the joint funding in equal shares for development and facilitation of the OpenAccess Project proposed from among and approved by 75% of voting Coalition members.

III. Cadence Responsibilities


Technology Cadence Responsibilities Coalition/Change Team Responsibilities
Through 1/1/2003 Until January 1, 2003, Cadence will be responsible for critical bug fixes (defined as those errors that are fatal and have no workaround and do not alter the behavior of the API.)

After the above date, Cadence may cede this responsibility to Si2
. The Coalition will limit the support of the Version 1 (C-Level) API specification to maintenance of its delivered state except for bug fixes or ports that do not alter the API behavior, so long as Cadence is complying with this Agreement.
Version 2 (C++ Level) API and reference database Cadence will be solely responsible for all Version 2 development decisions through 2002.

On December 31, 2002, Cadence shall provide to the Coalition an API Specification for planned code enhancements that shall be completed by June 30, 2003.

Until June 30, 2003, Cadence will be responsible only to; (a) fix critical bugs, (b) correct interoperability problems between tools that are API compliant (applies only to commercially-available EDA tools or Coalition- internal tools made available to Si2) and (c) make compliant any delivered code that does not meet the accepted specifications.
Starting January 1, 2003, Si2 will put in place a compliance program to validate: (a) critical bug reports, (b) interoperability problems between tools that are API compliant and (c) compliance of delivered code to the accepted specifications. Si2 will maintain this program. Si2 will supply a draft version of such program to Cadence on or prior to May 2002.

Between July 1, 2003 and June 30 2004 Cadence will also implement changes proposed by the Change Team provided that Cadence agrees with the proposed changes. Additionally, Cadence will propose to the Change Team any changes that it wishes to make and will not make those changes unless the Change Team agrees.

Beginning July 1, 2004, all OpenAccess Capabilities will be subject to full Change Team decision-making.
All Other OpenAccess Capability
Beginning January 1, 2003, Cadence will respond to Change Team requirements for capability implementation to be delivered no earlier than July 1, 2003.
Change Team will manage decisions effecting new or changed functionality and features.

Integration Services
Cadence serve as the integrator of all OpenAccess database software. Once a set of changes has been approved by the Change Team, Cadence has the first right of refusal to provide a just Cost/Time estimate within 15 business days for integrating the changes to the reference implementation. The Coalition has the option to having the changes integrated through a Coalition member third party company if one of the following conditions is true:

  • Cadence decides not to accept this particular job
  • Cadence doesn't respond within 15 business days
  • The estimate is proved to be unjust by the Change Team
  • If the Statement of Work is terminated as a result of a breach by Cadence

The job will commence after the Coalition and Cadence reach agreement on a signed work order and agreed upon delivery schedule. The project will be considered complete when the new reference code has passed a set of acceptance tests specified by the Coalition to ensure functionality and interoperability.

New versions of OpenAccess will be made available by Si2 through its OpenEDA www site.

Notwithstanding the above, in the event that the Coalition (or one or more of its members, on the Coalition's behalf) makes a bug fix, Cadence will make such change (or a functionally equivalent change) by the next regularly scheduled release. Such obligation will continue until the 12, 2002 source code release.

IV. Change Team

The Change Team shall be the approving body for any modifications to the OpenAccess API Specification and reference database implementation by the Community, and oversight of the OpenAccess technical roadmap.


The Change Team shall be comprised of not more than 12 members, with a maximum of five (5) representing EDA companies. The Change Team shall be led by two (2) architects, both of whom shall be members of the Change Team. As long as Cadence is a member of the Coalition, Cadence will have the right to appoint one of its employees as one of the architects to serve on the Change Team. The other architect shall be appointed by the Change Team and shall not be an employee of a commercial EDA company.

Requirements for Membership
The purpose of the Eligibility Requirements is to ensure that only those OpenAccess Community organizations with a demonstrable vested interest in the future of OpenAccess are permitted to make decisions regarding any changes to the API specification and reference database implementation.

Change Team membership is by majority election from among Coalition members for those candidate companies meeting the above qualifications plus the following:

  • A Change team member must be an employee of a Coalition member in good standing with significant EDA application development and/or integration experience with API based design flows.
  • A Change Team member should be able to devote the effort necessary to review and test database source code changes upon mutual agreement with the Change Team.

If any Change Team member can show substantial and reasonable cause that another Change Team member is not in compliance with the terms of the Coalition Participation Agreement and Change Team requirements, that member may propose that the cited Change Team member be removed from the Change Team. In such event, the Change Team shall vote on such proposal; the Change Team member will be removed from the Change Team upon an affirmative vote of at least nine (9) members. Should a Change Team member be removed in such fashion without breaching its obligations to Si2, that member may seek reelection to the Change Team for future terms.

Notwithstanding the above, in the event an individual ceases to be a Change Team member for any reason, including, that their company is found to be in violation of the license agreement, participation agreement or any other agreements relative to the participation agreement, then Si2 will facilitate the selection of a replacement by nomination and majority ballot among the voting members of the Coalition for the remainder of the term of the removed Change Team member. Until such time that a replacement is elected by the Coalition, the voting privileges of the removed member shall be ceded to the Change Team architects.

Change Team Voting Process
Decisions of the Change Team shall require a concurring vote of at least 9 of the Change Team members. If the Change Team temporarily has less than 12 members, and a proposal receives a 75% majority approval but not 9 votes, then the Architects (by unanimous vote) will make up the missing votes. Votes by a Change Team member may be made during attendance at the voting event, by electronic mail, by telephone, or through delegated proxy to an architect. If any Change Team member neglects to vote, such position shall be recorded as a "no" vote. Should the Change Team so vote, the Change Team may collectively delegate its proxy to the elected architects. If both architects agree to make a change, for which they have been granted decision authority by proxy, the change shall thereby be approved. If both architects agree not to make the change, or, if the architects disagree on whether to make the change, the change shall thereby be rejected. Rejected changes may be implemented through the OpenAccess Extensibility API.
