In this paper we describe a practical approach for modeling low level interfaces between software and hardware parts based on SysML operations. This method is intended to be applied for the development of drivers involved on what is classically called the “hardware abstraction layer” or the “basic software” which provide high level services for resources management on the top of a bare hardware platform. It is also an enabler for co-design processes since the design of hardware and software can be decoupled. In addition this approach is compatible with virtual prototyping technologies such as SystemC/TLM. An application to a simple a study case is provided for illustration purpose.
