Domain-specific languages (DSLs) are useful for capturing and reusing engineering expertise. They can formalize industrial patterns and practices while increasing the scalability of verification, because input programs are written at a higher level of abstraction. However, engineering new DSLs with custom verification is a non-trivial task in its own right, and usually requires programming language, formal methods, and automated theorem proving expertise.<\/p>\n
In this tutorial we present FORMULA 2.0, which is formal framework for developing DSLs. FORMULA specifications are succinct descriptions of DSLs, and specifications can be immediately connected to state-of-the-art analysis engines without additional expertise. FORMULA provides: (1) succinct specifications of DSLs and compilers, (2) efficient compilation and execution of input programs, (3) program synthesis and compiler verification.<\/p>\n
We take a unique approach to provide these features: Specifications are written as strongly-typed open-world logic programs. These specifications are highly declarative and easily express rich synthesis \/ verification problems. Automated reasoning is enabled by efficient symbolic execution of logic programs into quantifier-free sub-problems, which are dispatched to the state-of-the-art SMT solver Z3. FORMULA has been applied within Microsoft to develop DSLs for verifiable device drivers and protocols. It has been used by the automotive \/ embedded systems industries for software \/ hardware co-design and design-space exploration under hard resource allocation constraints. It is being used to develop semantic specifications for complex cyber-physical systems.<\/p>\n","protected":false},"excerpt":{"rendered":"
