International audienceThe PHYLOG project aims at offering a model-based software-aided certification framework for aeronautical systems based on multi/many-core architectures. Certifying such platforms will entail fulfilling the high level objectives of the MCP-CRI / CAST-32A position paper. To reach this general objective, we have defined a certification framework based on patterns to express any argumentation; as well as formal and automatic analyses to support the proof of the argumentation. In this paper, we will introduce the certification methodology and apply it on the KEYSTONE platform
