SystemC is a modeling language built as an extension of C++. Its growing popularity and the increasing complexity of designs have motivated research efforts aimed at the verification of SystemC models using assertionbased verification (ABV), where the designer asserts properties that capture the design intent in a formal language such as PSL or SVA. The model then can be verified against the properties using runtime or formal verification techniques. In this paper we focus on automated generation of runtime monitors from temporal properties. Our focus is on minimizing runtime overhead, rather than monitor size or monitor-generation time. We identify four issues in monitor generation: state minimization, alphabet representation, alphabet minimization, and monitor encoding. We conduct extensive experimentation and identify a combination of settings that offers the best performance in terms of runtime overhead.

“…Similar philosophy has been adopted by Karlsson et al [12], Ecker et al [7], and Pierre and Ferro [17], which likewise do not model the kernel. This may sound reasonable at first, but one soon realizes that many important properties require some knowledge of the state of the kernel.…”

Abstract-Monitoring temporal SystemC properties is crucial for the validation of functional and transaction-level models, yet the current SystemC standard provides no support for temporal specifications. In this work we describe a temporal monitoring framework for the SystemC specification language defined by Tabakov et al. at FMCAD'08. Our framework uses a very minimal modification of the SystemC kernel, exposing event notifications and simulation phases. The user code is instrumented to allow observation of the relevant parts of the model state. As proof of concept, we use the framework to specify and check properties of two SystemC models. We show that monitoring SystemC properties using this framework has reasonable overhead (0.01% -1%) and has decreasing marginal cost. Finally, we demonstrate that monitoring at different levels of abstraction requires very small changes to the specification and the generated monitors. Based on our empirical results we argue that the additional expressive powers and flexibility of the framework does not incur a serious performance hit.

A successful monitoring framework for SystemC requires access to internal variables of modules and channels, and the ability to trace the execution of threads and methods. We propose a framework for automatically instrumenting user code and exposing its state and syntax via automatically generated Aspect-Oriented Programming code and direct instrumentation. This allows monitoring the execution with a finegrained temporal resolution. Our tool, CHIMP, allows the users to declare specification primitives referring to the values of internal variables, the values of parameters passed to function calls, and function return values. Tracing execution of processes is enabled by allowing statements' execution or function calls to be used as atomic propositions. The correct behavior of the model can then be specified by forming temporal formulas and clock expressions using these primitives, without requiring manual instrumentation of the user code.
