    Abstract

    This paper presents a high-level temporal partitioning algorithm, which is able to split the VHDL description of a digital
    system into two equivalent subdescriptions. The primary goal of the algorithm is to obtain two area-balanced, time-independent
    partitions. The descriptions of these partitions can be separately simulated, synthesized and implemented as different configurations
    of a dynamically reconfigurable device. The partitioning principle is based on a directed task hypergraph. Each vertex of
    this hypergraph corresponds to one concurrent assignment of the description being analysed. The resources required for the
    physical implementation of each vertex are calculated by means of a simplified resource estimator. Time dependencies between
    vertices are denoted by hyperedges representing signals connecting appropriate concurrent assignments.
