Support for Holistic Response-Time Analysis in an Industrial Tool Suite: Implementation Issues, Experiences and a Case Study

Abstract

Abstract-The process of implementing and integrating state-of-the-art real-time analysis techniques with an existing industrial tool suite for the development of Distributed Realtime Embedded (DRE) systems offers many challenges. The implementer has to not only code and implement the analysis in the tool suite, but also deal with several issues such as extraction of unambiguous timing and tracing information from the design model. In this paper we present an implementation of the Holistic Response-Time Analysis (HRTA) as a plug-in for an industrial tool suite Rubus-ICE that is used for componentbased development of DRE systems. We discuss and solve the issues encountered and highlight the experiences gained during the process of implementation, integration and evaluation of HRTA plug-in. We also provide a proof of concept by modeling an automotive application (autonomous cruise control system) using component-based development and analyzing it with HRTA plug-in.

Response-time analysis of mixed messages in Controller Area Network with priority- and FIFO-queued nodes

“…The motivation for this work comes from the activity of implementing the holistic response-time analysis [26] in the existing industrial tool suite, Rubus-ICE [20,21], that provides a component-based development environment for resource constrained distributed real-time systems while supporting several high-level protocols for CAN.…”

Response time analysis for mixed messages in CAN supporting transmission abort requests

“…The extended analysis supports the Worst Case Response Time (WCRT) computation of CAN messages that are queued for transmission periodically, sporadically and both periodically and sporadically (mixed). This analysis has been implemented in the existing industrial tool suite, i.e., Rubus-ICE [8], [9], [10]. In [11], [12], Mubeen et al further extended the previous analysis [7] by integrating it with the analysis in [4] to support response time computation of mixed messages in CAN with priority-and FIFO-queued nodes.…”

Extending response-time analysis of mixed messages in CAN with controllers implementing non-abortable transmit buffers

“…This analysis has been implemented in the existing industrial tool suite, i.e., Rubus-ICE [11,12,13]. In [14,15], we further extended the previous analysis [10] by integrating it with the analysis in [5] to support response-time computation of mixed messages in CAN with priority-and FIFO-queued nodes.…”
