VaST Systems Announces 1-SOURCE Initiative; 1-SOURCE Unifies Architecture, Hardware and Software Design Through Standards-Based Interoperability and Key Virtual System Prototyping Technologies

SUNNYVALE, Calif.--(BUSINESS WIRE)--July 17, 2006--VaST -- the technology leader in embedded design -- today announced the 1-SOURCE initiative to unify the embedded system design flow. 1-SOURCE unifies the flow with a single standards-compliant, high-speed, cycle-accurate virtual processor model integrated with a series of standards-based virtual system prototyping technologies and third-party tool interfaces.

A major barrier to the adoption of virtual system prototypes (VSPs) has been the difficulty and complexity of making them work in the larger design flow. One root cause of complexity is the large number of processor model abstraction types, each with different timing, performance and functionality characteristics. Processor model abstraction types include programmers view (PV), programmers view with timing (PVT) and cycle-accurate view (CA). Thus, a design having 3 unique cores would require development and maintenance of an overwhelming nine processor models -- plus the numerous transaction interfaces required to handle communication between the different types of models.

The 1-SOURCE initiative solves this complexity problem with ONE processor model (1-SOURCE) satisfying performance and accuracy requirements, coupled with a series of innovative standards-based technologies and third-party tool interfaces. The 1-SOURCE initiative is defined by six major deliverables:

1. High-speed, cycle-accurate processor modeling technology
enabling a single 1-SOURCE model to deliver accuracy and performance
superior to the hybrid PV, PVT, CA approach. The same 1-SOURCE model
can be used for architecture, software, and hardware development.
Status - delivered.

2. Native OSCI 1666 SystemC support enabling standards-based
interoperability and high performance simulation. Status - delivered.

3. Standards-based communication model support that allows high
performance simulations using protocol-agnostic transaction models
such as OCP-IP TL2 and Greensocs(TM)/ Greenbus(TM). VaST is an active
member of both organizations and has significant experience and
intellectual property in this area. Status - in progress. (See press

4. Third-party tools interfaces that allow customers to use
virtual system prototypes with proprietary and third-party models and
tools (such as The Mathworks Simulink(R) and HDL models) and third
party simulators. Status - in progress.

5. Open platform export to other SystemC simulators allowing
customers to package and ship platforms created with VaST tools to
their customers who may use other SystemC tools. Status - in progress.

6. Deploying VaST's innovative, high speed and cycle-accurate
processor modeling technology to processor intellectual property (IP)
companies, allowing them to create and deploy 1-SOURCE virtual
processor models. Status - in progress.

"The 1-SOURCE initiative defines a new standards-based performance point for virtual system prototyping solutions. As a result of working closely with architects, hardware and software designers on leading embedded system design projects, the elements of 1-SOURCE are forged from real customer design activity," said Jeff Roane, director of marketing at VaST.

"We are deeply committed to furthering the productivity of our customers through compliance to standards and opening our modeling and simulation technology to users. The marketplace will continue to see a series of actions from VaST that support the 1-SOURCE initiative," commented Alain Labat, VaST president and CEO.
