Excel Software today released Universal Binary editions of MacA&D and MacTranslator for system and software modeling. MacA&D 2.1 runs three times as fast as version 2.0 on Apple's new Intel-based systems, according to the company, while MacTranslator 1.1 runs roughly five times as fast on Intel-based machines. MacA&D is a tool for system modeling and simulation, requirements management, structured analysis as well as design, and object-oriented modeling with UML and data modeling of information systems. MacTranslator scans source code to extract design information to a text file, which is imported into the MacA&D modeling tool to automatically generate UML class models, structure charts, and rich data models. MacA&D 2.1 is available for $500 for the standard edition or $2,000 for the developer edition, and requires Mac OS X 10.1 or later. MacTranslator 1.1 is available for $500.
