ARREST: an interactive graphic analysis tool for VLSI arrays

The authors present a graphical CAD tool, Array Estimator (ARREST), for VLSI array architectures. In real VLSI arrays, piece-wise regular computations are spread across space and time and occur at a fine-grain, which can make visualization quite difficult. Consequently, a graphical interface environment is desirable to enhance the design, verification, and analysis of VLSI arrays by providing feedback at all levels of the design process. ARREST reads a high level description of structured VLSI algorithms in terms of affine recurrence equations (AREs) and permits a broad range of transformations on the algorithm. The system does not target a fully automated design process, instead it provides a designer with a means to systematically explore various array architectures and evaluate design trade-offs between VLSI cost and performance. To allow a human designer better insight into the design process, ARREST uses the Xt/MOTIF window system for graphics and interfaces to the Cadence VERILOG simulator
