Preface
Electronic System Level Design, or ESL Design, is generally understood as the set of tools, methodologies and design techniques applied to modern electronic systems design, from high-end chips and systems, to embedded devices, to integrated hardware and software systems. Given the complexity of current systems, advanced tools and methodologies have become absolutely essential to achieve the necessary productivity, quality, cost and performance expected in a design process. One of the important tenets in ESL Design is the need for early design analysis. This is done mainly through high-level modeling and simulation, performance and power analysis and functional verification, before committing the design to lower-levels of abstraction aimed at synthesis and optimization. This is especially true for complex systems involving different types of components such as processors, custom blocks and software. In fact, it may be totally impractical to simulate such systems at a lowlevel of representation such as register-transfer level, due to extremely long simulation times. High-level models are simpler to write, understand, optimize and debug than lower-level models, and they can simulate significantly faster. The more the design can be refined, optimized and verified at a high-level of abstraction, the higher the overall design productivity, the better the quality and consequently the lower the cost of the final result. However, high-level models and development environments are not without their own difficulties. It is not simple to write a high-level model at the appropriate abstraction level which will result in the best trade-off between architectural details and simulation speed. For
