FORMULA 2.0: Formal Specifications for Verification and Synthesis
Formula specifications are highly declarative logic programs that can express rich synthesis and verification problems.
FORMULA 2.0 is framework for formally specifying domain-specific languages (DSLs) and model transformations. 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.
FORMULA 2.0 provides these features in a unique way: 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 constraints, 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 under hard resource allocation constraints.
