PaperTrail is a Ruby on Rails gem providing version tracking for ActiveRecord models. It stores every change to records, enabling auditing, undo/redo of updates, and historical reconstruction of model states. Designed for traceability, compliance, and temporal querying across Rails applications.
Synthesizing embedded control software from formal specifications
autoCode4 is an engine that synthesizes controllers from formal specifications described under a subset of linear temporal logic (LTL).
Importantly, it synthesizes synchronous dataflow controllers (in Lustre or in Ptolemy II form) and maintains requirement-to-code traceability. Such feature is mandated in developing safety-critical systems and are considered essential for specification validation or integrating manual implementation such as legacy code.
The LTL specification captures the desired behavior of a controller where the environment takes the first move (i.e., sense/input then react/output), so the synthesized controller can be viewed as a Mealy machine.
