Latest Version of StateMate Magnum Adds VisSim Software to Offer Breakthrough Hybrid System Modeling

Release 2.0 Integrates VisSim with Statemate MAGNUM 2.0

ANDOVER, MA, August 25, 1999 — I-Logix Inc., a leading provider of enterprise solutions for embedded applications development, today introduced Statemate MAGNUM 2.0, the latest version of its market-leading embedded systems design software. Statemate MAGNUM 2.0 offers users hybrid system modeling with its Continuous Modeler. The Continuous Modeler is based on Visual Solutions’ VisSim software, that has been tightly integrated with Statemate MAGNUM 2.0. The Hybrid modeling capability significantly broadens the market for Statemate MAGNUM by enabling it to model continuous and hybrid systems (as opposed to only discrete systems).

"I-Logix’ commitment to insure that Statemate MAGNUM remains the market-leading systems engineering tool in the automotive and aerospace markets is demonstrated in this release," said Gene Robinson, president and CEO of I-Logix. "The addition of the Continuous Modeler brings all the capabilities needed to completely model any embedded system whether it is primarily discrete, continuous, or hybrid in nature.

Hybrid Modeling
With its latest release, I-Logix’ Statemate MAGNUM Continuous Modeler becomes the first tool to combine the domains of functional decomposition, discrete behavior, and continuous time behavior to enable hybrid specifications of complete embedded systems. The nature of most embedded systems found in the automotive and aerospace industries is such that an embedded controller is used to interact with both physical systems and the user. Statemate MAGNUM allows the user to break the system down into components, and to describe the behavior of the reactive or logical components of the system or the environment. With the addition of the Continuous Modeler, the user can also define the dynamics of the physical elements with which the controller acts, along with describing any closed loop control equations which interact with these physical elements. Examples where this capability is used in the automotive industry include cruise control and power windows, and in aerospace, for automatic pilot and missile trajectory systems.

The Continuous Modeler differs from other hybrid solutions by capturing the entire system behavior through a top-down approach, rather than only the hybrid algorithms using a bottoms-up approach. Users can now describe the entire embedded system with the notation most suitable for the type of behavior being specified. This can increase productivity by reducing time spent modeling and simulating the system, reduce costs by finding errors earlier in the process when rectification is easiest, and provide greater communication between design team members.

The Continuous Modeler is enabled by VisSim, a product developed by Visual Solutions, Inc., a pioneer in the development of Windows-based software for the modeling and simulation of dynamic systems. After careful evaluation of leading modeling and simulation packages, I-Logix signed an OEM agreement with Visual Solutions that allows the integration of VisSim with Statemate MAGNUM giving I-Logix the right to sell, market, and support this technology. I-Logix chose Visual Solutions’ "best-in-class" VisSim product for its drag and drop block diagram design approach, high-level model capability, and tight integration with Statemate MAGNUM 2.0 at the modeling, simulation, code generation and documentation generation levels. Moreover, VisSim has a successful track record, as evidenced by its recent 1999 Readers' Choice Award from Control Magazine, with a first place in the Software: Simulation Category.

"We are very excited to be working with I-Logix as an OEM partner and are proud of the fact they chose our VisSim software technology for the Statemate MAGNUM Continuous Modeler," said John Gould, vice president of sales and marketing at Visual Solutions, Inc. "The top down, integrated hybrid modeling solution now available with Release 2.0 will help users get products to market faster and provide greater assurance that the product will perform as specified. I-Logix’ position in the automotive and aerospace markets, combined with a strong sales, marketing and support organization, makes them an excellent company to bring this technology to market. We look forward to working with I-Logix and its customers to make this innovative product a success."
