It is therefore essential to develop good tools for exploring a wide range of design choices at these early stages where the design space is very large. This paper provides an overview of our system-level modeling and simulation environment Sesame which aims at efficient design space exploration of embedded multimedia system architectures. Taking Sesame as a basis we discuss many important key concepts in early systems evaluation such as Y-chart-based systems modeling design space pruning and exploration trace-driven cosimulation and model calibration.

INTRODUCTION The ever increasing complexity of modern embedded systems has led to the emergence of system-level design 1 . High-level modeling and simulation which allows for capturing the behavior of system components and their interactions at a high level of abstraction plays a key role in systemlevel design. Because high-level models usually require less modeling effort and execute faster they are especially well suited for the early design stages where the design space is very
