Generating SystemC Implementations for Clock Constraints Specified in UML/MARTE CCSL
Judith M. Peters, Robert Wille, Rolf Drechsler · 2014
Due to the increasing complexity of today's embedded systems, the design on higher levels of abstraction becomes more and more important. In this context, modeling languages such as UML and its profile MARTE received significant attention in the recent past. They provide formal descriptions that can be exploited to automatically generate initial implementations of a system e.g. In SystemC. While corresponding approaches have been developed in the past, they often focused on functional specifications. Besides that, also non-functional behavior such as clocking constraints needs to be considered in this process. In this work, we propose an approach which addresses this gap. Given a formal specification of clocking constraints specified in the Clock Constraint Specification Language (CCSL, a MARTE accessory), we propose an automatic code generation scheme which enriches an existing SystemC implementation by a module triggering the desired clocks in the system.
