I-Logix was a company specializing in collaborative Model-driven development (MDD) solutions tailored for system design and software creation, with a particular emphasis on real-time embedded systems. Established in 1987 and headquartered in Andover, Massachusetts, the firm focused on products that enhanced teamwork among engineers developing embedded systems. Additionally, I-Logix participated as a member of the UML Partners, a coalition responsible for the development of the Unified Modeling Language (UML).
History
The origins of I-Logix trace back to April 1984 in Israel, where it was initially founded as AdCad Ltd. by David Harel, Amir Pnueli, and brothers Ido and Hagi Lachover. The company’s mission was to commercialize a tool that supported statecharts, based on David Harel’s research at the Weizmann Institute of Science. Harel had created statecharts during his consultancy on the Lavi Aircraft project for Israel Aerospace Industries, devising a novel approach to designing avionics systems.
By 1986, AdCad had developed Statemate, a software application focused on functional decomposition governed by statecharts. Statemate enabled users to build, analyze, document, and maintain models, offering full execution of statecharts and generating code initially in Ada and later transitioning to C.
In 1987, the company restructured as I-Logix Inc., relocating its base to the United States, while AdCad became its research and development division under the name I-Logix Israel, Ltd.
The year 1996 saw I-Logix introduce Rhapsody, an object-oriented modeling tool designed specifically for software engineers, distinguishing it from Statemate’s primary focus.
December 1999 marked a significant milestone when I-Logix raised $10 million through investments from North Bridge Venture Partners and Deutsche Telekom, aiming to broaden its international sales network.
In 2001, I-Logix expanded its portfolio by acquiring the iNOTION product life-cycle management (PLM) technology from KLA-Tencor, signaling a strategic move toward platforms that support component reuse.
Throughout the 2000s, I-Logix established itself as a leading provider in embedded systems and software development tools, securing prominent clients such as General Motors,[1] Lockheed Martin (notably for the Joint Strike Fighter F-35 program), and BAE Systems (for the Eurofighter Typhoon program).
In March 2006, I-Logix was acquired by Telelogic AB for $80 million. Following this acquisition, it became Telelogic’s embedded modeling division and the I-Logix brand was discontinued. Subsequently, in April 2008, Telelogic itself was acquired by IBM, leading to integration of I-Logix’s product lines into IBM’s Rational Software division.
Recognition of the Statemate development team came in 2007 when they received the prestigious ACM Software System Award for their groundbreaking contributions to the design of complex reactive systems:
Products
Prior to its acquisition, I-Logix developed key tools such as Statemate and Rhapsody (currently marketed as IBM Rational Rhapsody). These products found widespread adoption among top-tier automotive and aerospace/defense manufacturers and their suppliers. Under IBM’s stewardship, growth for Statemate has plateaued while Rhapsody is increasingly promoted as its successor.
