Description: vlogsl: a strategy language for simulation-based verification of hardware. Languages such as SystemVerilog and \(e\) play an important role in contemporary hardware verification methodology. Through direct, language-level support for notions like constrained randoms, functional coverage, assertions, and so forth, they help verification engineers adopt useful paradigms. This paper demonstrates the usefulness of a new strategy-based paradigm for hardware test generation which is not directly supported by any language we are aware of. A strategy is formed by coordinating multiple simulations toward achieving a high-level goal, such as the generation of a targeted stimulus driving the device through a specific behavior. Strategies are made possible at the language level through constructs exerting meta-level control over simulation, making simulation traces first-class data objects that can be stored, queried, and otherwise manipulated programmatically. These ideas are embodied in a language and tool, called url{vlogsl}. url{vlogsl} is a domain-specific embedded language in Haskell, providing a sophisticated set of strategy language features, including first-order symbolic simulation and integration with an SMT solver. We motivate strategies, describe url{vlogsl}, present several pedagogical examples using url{vlogsl}, and finally a larger example involving an open-source I\(^{2}\)C bus master.
