Synopsys Rolls Out Verification IP for AMBA 3 AXI Protocol Standard

12/8/2004 - Synopsys, Inc. (Nasdaq:SNPS), a world leader in semiconductor design software, announced the general availability of the industry's first verification intellectual property (VIP) suite for the AMBATM 3 AXI protocol. The DesignWare® VIP for the AMBA 3 AXI protocol, created through the collaboration of industry leaders Synopsys and ARM®, builds on the success of the AMBA AHBTM interface, the most widely adopted de-facto standard interface already used in hundreds of embedded processor-based designs. The AMBA 3 AXI protocol is the next-generation of the AMBA family of on-chip interface protocols, targeted at high-performance, low latency designs and is supported natively by new ARM embedded processors, including the ARM1176JZ-STM processor, the ARM1156T2F-STM processor and future CortexTM family processors. DesignWare Library and DesignWare Verification Library customers gain immediate access to the AMBA 3 AXI VIP for no additional charge.

The DesignWare VIP for AMBA 3 AXI protocol embodies extensive protocol expertise and provides stimulus generation, response creation and bus interface protocol checking, required for successful SoC verification. Synopsys DesignWare VIP can save designers' 75 percent or more in testbench development time and effort by enabling the use of a layered, coverage-driven, constrained random verification environment. Individual tests, various arbitration schemes and multiple component interactions can all be tested very early in the design process.

"High quality VIP is an essential element for the successful development of complex system-on-chip designs based around high-performance ARM11TM family processors that use AMBA 3 interfaces," said John Cornish, director of Product Marketing at ARM. "The launch of Synopsys DesignWare VIP for the AMBA 3 AXI protocol highlights the increasingly wide adoption of interfaces from the AMBA 3 protocol family. Having it available within Synopsys' DesignWare Library and Verification Library instantly puts a high quality verification solution for the AMBA 3 AXI protocol into a broad customer base with world-class Synopsys support."

"Synopsys continues to give its DesignWare users high quality VIP to reduce risk and speed time to results," said Guri Stark, vice president of Marketing in the Solutions Group at Synopsys. "The availability of the VIP for AMBA 3 AXI protocol in DesignWare Libraries should help speed the development of the next generation of high-performance designs."

There are four components of the DesignWare VIP for AMBA 3 AXI protocol: configurable interconnect, master, slave and monitor models. The interconnect VIP allows the verification of design blocks to start before the actual interconnect RTL is available. Within a dynamic simulation, the designer uses the master and slave VIP components to generate transactions and responses. In addition to bus protocol checking, the VIP monitor automatically collects transaction coverage data and provides advanced debugging hooks for the testbench environment. There is also built-in support for coverage-driven constrained-random test generation through a reusable, layered verification approach. Synopsys and ARM are working in close collaboration to standardize VIP stimulus and control. In the future, this is expected to enable Synopsys' DesignWare VIP components to run the ARM-supplied eXtensible Verification Component (XVC) tests out of the box.

Pricing and Availability
The DesignWare VIP for AMBA 3 AXI protocol is available today and is included in the DesignWare Library and the DesignWare Verification Library for no additional cost to existing licensees. The DesignWare Library and the DesignWare Verification Library (a subset of the DesignWare Library) are available on a subscription or perpetual license basis.
