Verified Runtime Validation for Partially Observable Hybrid Systems [article]

Stefan Mitsch, André Platzer
2019 arXiv   pre-print
This makes runtime validation a crucial step to monitor whether the model assumptions hold for the real system implementation.  ...  For an unbroken chain of correctness guarantees, we, thus, synthesize runtime monitors in a provably correct way from provably safe hybrid system models.  ...  To concisely handle intervals that we will need for tolerances in partially observable hybrid systems, we use shortcut notation.  ...

HAVE: Detecting Atomicity Violations via Integrated Dynamic and Static Analysis [chapter]

Qichang Chen, Liqiang Wang, Zijiang Yang, Scott D. Stoller
2009 Lecture Notes in Computer Science  
The static summaries are then instantiated with runtime values during dynamic executions to speculatively approximate the behaviors of branches that are not taken.  ...  Compared to dynamic analysis, the hybrid approach is able to detect atomicity violations in unexecuted parts of the code. Compared to static analysis, the hybrid approach produces fewer false alarms.  ...  Our current implementation does not use Theorem 1, because our system looks for potential atomicity violations; it does not try to verify atomicity.  ...

Formally enhanced runtime verification to ensure NoC functional correctness

Ritesh Parikh, Valeria Bertacco
2011 Proceedings of the 44th Annual IEEE/ACM International Symposium on Microarchitecture - MICRO-44 '11  
Formal verification, due to its scalability limitations, is used to verify the smaller modules, such as individual router components.  ...  As silicon technology scales, modern processors and embedded systems are rapidly shifting towards complex chip multi-processor (CMP) and system-on-chip (SoC) designs, comprising several processor cores  ...  Acknowledgments This work was developed with partial support from the National Science Foundation and the Gigascale Systems Research Center.

The e-ACSL perspective on runtime assertion checking

Julien Signoles
2021 Proceedings of the 5th ACM International Workshop on Verification and mOnitoring at Runtime EXecution  
Runtime Assertion Checking (RAC) is the discipline of verifying program assertions at runtime, i.e. when executing the code.  ...  Here, we revisit these three RAC's research areas by emphasizing the works done in E-ACSL, which is both a BISL and a RAC tool for C code. We also compare it to others languages and tools.  ...  Indeed, pure methods are easy to execute for runtime assertion checkers, but lead to several issues for consistently verify them for deductive verifiers [35] .  ...

Towards the Verification of Safety-critical Autonomous Systems in Dynamic Environments

Adina Aniculaesei, Daniel Arnsberger, Falk Howar, Andreas Rausch
2016 Electronic Proceedings in Theoretical Computer Science  
For the runtime phase, we build a monitor to check whether the assumptions made at design time are also correct at run time.  ...  If the current system observations of the environment do not correspond to the initial system assumptions, the monitor sends feedback to the system and the system enters a passive safe state.  ...  During its runtime, the system S operates in its environment E and a monitor Monitor SA observes both in order to check whether the system assumptions made during design time are still valid at runtime  ...

Runtime verification for autonomous spacecraft software

A. Goldberg, K. Havelund, C. McGann
2005 2005 IEEE Aerospace Conference  
Software is usually an essential part of such systems. However, adaptation of autonomy software is limited by its complexity and the difficulty of verifying and validating it.  ...  We describe an approach named runtime verification for testing autonomy software. Runtime verification is a technique for generating test oracles from abstract specifications of expected behavior.  ...  This is intended to verify the planner but not to validate the model. The Livingstone PathFinder (LPF) [12] is a system for testing Livingstone models.  ...

2015 Proceedings of the International Conference for High Performance Computing, Networking, Storage and Analysis on - SC '15  
Relative debugging is particularly effective when code is migrated from one platform to another, and this is of significant interest for hybrid computer architectures containing CPUs accelerators or coprocessors  ...  In this paper we extend relative debugging to support porting stencil computation on a hybrid computer.  ...  However, validating the global state of a hybrid program at runtime is rarely provided.  ...
