A Holistic Approach in Embedded System Development

Abstract

We present pState, a tool for developing "complex" embedded systems by integrating validation into the design process. The goal is to reduce validation time. To this end, qualitative and quantitative properties are specified in system models expressed as pCharts, an extended version of hierarchical state machines. These properties are specified in an intuitive way such that they can be written by engineers who are domain experts, without needing to be familiar with temporal logic. From the system model, executable code that preserves the verified properties is generated. The design is documented on the model and the documentation is passed as comments into the generated code. On the series of examples we illustrate how models and properties are specified using pState.Comment: In Proceedings F-IDE 2015, arXiv:1508.0338

“…• For the quantitative analysis, costs can be attached to transitions and states (state costs accumulate linearly with time). Queries for the (minimal and maximal) reachability probability and for expected (maximal and minimal) costs can be attached to states [29].…”

“…• Comments can be embedded in the charts and are preserved in the generated executable code. If they are attached to states and transitions, then they are placed in the generated code where the corresponding variables are declared or transition is taken [29].…”
