A model-based I/O interface synthesis framework for the cross-platform software modeling

In model-based development, executable software (e.g., C or Java code) can be generated from a high-level model using a code generator. However, the execution of the generated software on a target platform remains a challenge due to a mismatch in communication semantics assumed by the model and the platform-dependent software (e.g., sampling/actuation routines). This paper proposes an input/output (I/O) interface module that bridges this semantic gap by means of buffers and interface policies, which explicitly capture the information required to adapt the model´s communication semantics to that of the platform. We present a framework that can be used to systematically synthesize - directly from the model - the I/O interfaces and accompanying APIs that the generated software and the platform-dependent software need to communicate with one another. Our interface policies can also encode relaxations of a model semantics that may not be implementable, thus making derivations of the implemented systems from the model traceable. We illustrate the applicability and the benefits of our framework with a case study of an infusion pump.
