SysML in Realtime-Embedded-System.pdf

In this paper, we first introduce the MADES language, which enables rapid system design and specification that can be then taken by underlying MADES tools for goals such as simulation or code generation. Finally, we illustrate the various concepts present in the MADES language by means of a car collision avoidance system case study.

SysML 标准 v1.5, 2017年5月发布

SysML is designed to provide simple but powerful constructs for modeling a wide range of systems engineering problems. It is particularly effective in specifying requirements, structure, behavior, allocations, and constraints on system properties to support engineering analysis. The language is intended to support multiple processes and methods such as structured, object-oriented, and others, but each methodology may impose additional constraints on how a construct or diagram kind may be used. This version of the language supports most, but not all, of the requirements of the UML for Systems Engineering RFP, as shown in the Requirements Traceability referenced by Annex F. These gaps are intended to be addressed in future versions of SysML as indicated in the matrix.

Virtual Machines for RTEMS Development

This page describes the VirtualBox (http://www.virtualbox.org/) image of CentOS 6.2 with the RTEMS 4.11 development environment preinstalled for the i386 and SPARC targets. BSPs within these CPU families can be run on simulators inside the virtual CentOS 6.2 environment. The CentOS install has been stripped of multimedia and office applications to save space.
