A design environment for high performance VLSI signal processing

An environment for the full-custom design of high-sample-rate digital signal processing (DSP) VLSI circuits is described. An overall design methodology that allows for tradeoffs between algorithms, architecture, and layout is presented. Key CAD tools used in this methodology include architecture mapping, generators, symbolic layout, clock network analysis, and timing simulation. These tools allow designers to move rapidly from specification to layout while keeping a close check on performance parameters such as speed and power dissipation. Two high-speed video chips that were designed using these techniques are described.< >
