EXIST: an interactive VLSI architectural environment

EXIST (Exploration in Smalltalk) is an integrated environment for exploratory VLSI architectural design implemented in the Smalltalk-80 environment. It consists of a functional simulator (INSIST), a floorplanner (FLOORIST) and a database (DATABIST). EXIST contains several unique features including: editing while in simulation, manual and automated hierarchical floorplan optimization, and user-friendly interface based on the model-view controller paradigm of Smalltalk. These features make EXIST a promising environment for exploration of alternative VLSI architectures, such as RISC (reduced instruction-set computer) controllers.<
