This report presents a survey of current simulation tools in the area of integrated control and real-time systems design. Each tool is presented with a quick overview followed by a more detailed section describing comparative aspects of the tool. These aspects describe the context and purpose of the tool (scenarios, development stages, activities, and qualities/constraints being addressed) and the actual tool technology (tool architecture, inputs, outputs, modeling content, extensibility and availability). The tools presented in the survey are the following; Jitterbug and TrueTime from the Department of Automatic Control at Lund University, Sweden, AIDA and XILO from the Department of Machine Design at the Royal Institute of Technology, Sweden, Ptolemy II from the Department of Electrical Engineering and Computer Sciences at Berkeley, California, RTSIM from the RETIS Laboratory, Pisa, Italy, and Syndex and Orccad from INRIA, France. The survey also briefly describes some existing commercial tools related to the area of real-time control systems. (Less)

Tools for Real-Time Control Systems Co-Design - A Survey

Increasing needs for optimized designs and for handling the dependencies among control systems and their real-time implementation, cause a resulting need for tools that have the abilities to support design across these traditional discipline boundaries. Tools supporting such co-design provide new opportunities in developing cost-efficient, dependable and robust solutions where the interactions between control and implementation engineers can be improved, and where further possibilities are obtained by increasing the information flow between the control system and the hardware/software platform during run-time. Work on codesign has the important effect to stimulate new theoretical research directions where more work is needed because of the lack of theory and methods in the field. Co-design related to embedded control system is a fairly new area and most of the methods and theory developed so far are aimed at analysis rather than synthesis. A further great challenge is that of model and tool integration, where there are needs to coordinate and integrate the multitude of aspects and specialized models/tools that are used in the development of embedded control systems. This survey sets the context of embedded control systems development describing what is achievable with current generation industrial tools. The context is further elaborated by discussing categories of tools from different related research disciplines. A set of representative co-design tools are then described in depth and discussed.

Modelling of Distributed Real-Time Control Systems An Approach for Design and Early Analysis

Real-time embedded applications such as signal-processing, surveillance and tracking, data fusion, and automated target recognition need parallel processors to meet their performance requirements. Unfortunately the task of developing the application-software, which must not only make efficient use of the available parallelism but must also integrate the many algorithms that comprise it, is extremely difficult. Current software design methods, including object oriented design methods, do not help in this regard as they are geared primarily for the design of sequential software.This paper presents an overview of the Parallel Scalable Design Toolset (PSDT) being developed at Honeywell to support the design and development of real-time embedded parallel software. Software designers can use PSDT to graphically specify parallelism across collections of objects and within objects, and synchronization of data and control flows. They can also compose parallel subtasks into tasks that may in turn be a part of other tasks.PSDT can support different domain-specific parallelization paradigms. Each paradigm defines composition rules and constraints on inter- and intra-object parallelism. Since domain-specific paradigms add additional structure to the program, tools for parallelism analysis, partitioning, mapping, and code generation are able to produce near-optimum results.A prototype of the PSDT toolset is operational including a domain-specific paradigm for deterministic data-parallel periodic applications. Support for other domains and heterogenous processing architectures is being added.
