Telelogic's latest SDL Suite 6.0 Expands Functionality for Next-Generation Protocol Development

SDL Suite 6.0 supports automated Model-Driven Development (MDD) workflows, which reduce development time and costs. New features enable engineers to optimize their 2G and 3G wireless systems development process, while preparing users for upcoming 4G systems. SDL Suite 6.0 also includes automation features to handle the increased call reliability and data throughput of today’s wireless systems.



The restructured execution kernel in SDL Suite 6.0 increases design flexibility and improves protocol development for next-generation wireless systems by enabling engineers to:

• Manage increased system resources

• Work with many more timers

• Trade off between optimized performance and minimized resources



While the SDL language is acknowledged as the best design and implementation approach for protocols, a key implementation issue is always scaling from a verified protocol specification to an implementation with many concurrent instances, said Rick Reed, Rapporteur and Group Chair, International Telecommunication Union, Telecommunication Standardization Sector (Q.11/17). Such scaling depends on the run-time system kernel for SDL, which is usually tool-vendor specific. The revised kernel that can handle large numbers (thousands) of timers and instances in one of the major telecoms industry tools, Telelogic SDL Suite 6.0, should therefore be an important, positive factor in the provision of modern-day, complex and high-performance communications protocols.



Via its integration with Telelogic Rhapsody®, the leading UML-based MDD solution for embedded and real-time development, SDL Suite 6.0 provides a powerful, new end-to-end UML/SDL solution that reduces development time and boosts product quality. This combination of MDD approaches fully automates the development, validation, code generation and testing of today’s complex communications applications and protocols.



SDL Suite 6.0 also supports Linux Host and Unicode. Linux support allows developers to leverage a common OS between host and embedded device streamlining testing, while Unicode enables globally distributed teams to work in their natural design environment, lowering costs and increasing developer productivity.



The SDL Suite 6.0 offers full SDL and TTCN support for the Windows Vista platform. The average cost for an SDL Suite 6.0 development system is $17,900, including model creation, execution, code generation and test generation. In addition, each SDL Suite 6.0 user under current maintenance will receive a free copy of the Rhapsody Systems Architect modeling tool and the integration with SDL Suite 6.0.
