Modern Field Programmable Gate Arrays (FPGAs) offer a solution to several issues related to real-time on-board systems, such as guaranteed execution time. They are currently considered as target platforms for space applications. However, the complexity of producing circuits on these components poses a challenge to their widespread adoption. To address this issue, high-level synthesis tools provide another layer of abstraction above the logic circuit design process, for example compiling C code into Hardware Description Languages such as VHDL or Verilog. However, high-level synthesis results are poorly predictable and do not guarantee the efficient use of recent FPGA capabilities provided by new primitives like digital signal processor or random-access memory. In this paper we propose a compilation chain dedicated to reactive systems, ie. controllers, providing a more predictable synthesis process for critical embedded control applications. The implemented solution demonstrates timing performance equivalent to the traditional synthesis process with a more predictable result.

SysML is a standard language that permits to model systems of any type such as plane, ships and software intensive systems. Software Product Line large scale reuse approach has demonstrated its success. The industry provides benefits in term of cost savings and acceleration of time to maket. The available literature indicates that there have been efforts to enhance the capability of SysML in handling product families. However, these attempts are not yet fully systematic, and there remains a significant amount of work to be undertaken in this area. In this present paper, we deal with the SysML Block Diagram in order to investigate to what extent it permits variability representation and how it can evolve during the system evolution or when agility is needed. We want to capitalize on the knowledge necessary for block diagram extention and evolution and take advantage of knowledge from Product Line domain engineering and application engineering. So, we decide to use an ontology which is an articifial intelligence artifact. An ontology is a powerful mean to represent knowledge and reason about it. Here, we use the ontology to help decision making for Block diagram evolution as well.
