A methodology and design tools to support system-level VLSI design

System-level design involves making major design decisions without having accurate information on the eventual system characteristics. This paper presents a novel constraint-driven methodology to support system-level design. The software assists a designer or a tool in partitioning behavioral specifications onto multiple VLSI chips and in system design while satisfying hard constraints such as individual chip areas, chip pin counts, system throughput (inverse of system initiation interval) and system latency (delay). The software uses search and estimation techniques to perform comprehensive design-space exploration and evaluates partitions supplied by the user or by other synthesis software. The technique determines what design characteristics each partition must possess in order to satisfy area, pin, throughput and latency constraints. The paper also includes results of extensive experiments with the methodology.<
