The development of SoC involves different activities, usually driven by specialists. These specialists use specific languages and tools to manipulate their specific concepts. The problem is that the multiple views of the system are split into different tools with redundant information. It makes it difficult to ensure consistency as well as to change from one tool to another. We propose a multi-view model where each view represents the specialist concepts in a tool-agnostic manner. The model can be kept consistent by using explicit associations instead of redundancy and tool transformation can be performed to analysis-specific tools. The approach is based on UML and two of its extensions: MARTE and SysML. It is illustrated by adding specific views to specify power management techniques. The resulting model is then transformed into a tool-specific model; \ie a model for Docea Aceplorer, a power analysis tool.
