This state-of-the-art survey gives a systematic presentation of recent advances in the design and validation of computer architectures. Based on advanced research ideas and approaches, and written by eminent researchers in the field, seven chapters cover the whole range from computer aided high-level design of VLSI circuits and systems to layout and testable design, including modeling and synthesis of behavior, of control, and of dataflow, cell based logic optimization, machine assisted verification, and virtual machine design. The chapters presuppose only basic familiarity with computer architecture. They are self-contained and lead the reader gently and informatively to the forefront of current research. A special feature of the book is the comprehensive range of architecture design and validation topics covered, giving the reader a clear view of the problems and of advanced techniques for their solution.
