Denali Chosen by IBM to Deploy New Development Toolkits for Power Architecture(TM)

Denali to Deliver Complete Verification and Compliance Tools to Support Power Architecture-Based Designs Using IBM CoreConnect(TM) Technology IBM PARTNERWORLD CONFERENCE, LAS VEGAS -- March 13, 2006 -- Denali Software today announced an agreement with IBM through which Denali will develop and deploy a comprehensive toolkit of verification and compliance software for developers of Power Architecture-based designs that use the IBM CoreConnect(TM) on-chip bus technology.

The toolkits will be distributed as part of Denali's PureSpec(TM) verification intellectual property (IP) and PureSuite(TM) compliance product offerings that are compatible with all major design and verification tool platforms, and can easily be implemented in any chip development flow. The availability of high-quality, platform-independent toolkits helps developers to design and verify system-on-chips (SoCs) that use the IBM Power Architecture.

Denali, a member of Power.org, will work in close collaboration with IBM to develop verification IP, testbenches, and compliance suites for the PLB-4 (Processor Local Bus) specification, which is the current, and widely used version of IBM's CoreConnect(TM) on-chip bus specification for Power Architecture-based designs. As part of the ongoing work, Denali will continue collaborative development of toolkits for PLB-5 and future generations of the PLB specifications. The resulting PureSpec-PLB and PureSuite-PLB toolkit products from Denali will provide developers with a comprehensive environment for current and future generations Power Architecture-based designs using IBM's CoreConnect on-chip bus technology.

"This is another example of the growing ecosystem of support for Power Architecture that is Power.org," says Nigel Beck, vice president, technology marketing, IBM Systems & Technology Group and chairman of Power.org. "The Denali toolkits will certainly help drive the design and acceptance of current and next-generations chip that use Power Architecture, which offers the broadest market and application coverage of any instruction set architecture today."

"The growing momentum behind the Power Architecture is very impressive," adds David Lin, vice president, product marketing, Denali Software. "This new development is a natural extension of our long-standing relationship with IBM, and demonstrates a commitment to the Power Architecture as an open standard. PureSpec verification IP products are already in wide use throughout the industry, and Denali will now leverage its extensive channel and technical support resources to deploy toolkits for Power Architecture based designs. The availability of toolkits built on Denali's proven, platform-independent verification IP gives designers low-risk path for developing of Power Architecture based systems. That's a big win for everyone."

About Denali PureSpec and PureSuite Products

PureSpec verification IP is the most widely used product for verifying functionality, compliance and interoperability of standard interfaces at the pre-silicon stage of chip or IP core development. PureSpec verification IP includes a configurable bus functional model (BFM), protocol monitor, and complete assertion library for all components in the topology, including the host and one or multiple devices.

PureSpec additionally provides an integrated data generation engine to help drive defined, pseudo-random bus traffic at all layers. A cumulative coverage database capability ensures that the overall test plan sufficiently exercises the design.

PureSuite is a comprehensive test suite product, containing pre-configured tests for exercising specific bus protocol, functionality, corner cases, and compliance conditions. PureSuite maps individual tests to all items defined in the bus protocol specification, and includes hundreds of additional tests designed to exercise other specific corner conditions. Used with PureSpec verification IP, PureSuite can automatically select and configure individual tests based on the specific bus or device configurations for the design under test, and other devices in the system. PureSuite automatically maintains a cumulative report of compliance results listing the pass/fail status for all tests executed with the design.

Hardware developers use PureSpec and PureSuite to enable a direct translation from test plan definition to implementation, resulting in dramatic reductions in the overall chip development cycle. For more information, visit: http://www.denali.com/products_purespec.html .
