1. A reconfigurable electronic system comprising:

  • a plurality of reprogrammable logic modules, each logic module having a plurality of pins for communicating signals external to the logic module and a plurality of logic elements for implementing logic in hardware;

    inter-module connections between pins of different logic modules; and

    a configurer for automatically configuring each logic module to define a partition of a specified target circuit with communications between the partitions of the target circuit being provided through pins and inter-module connections,a partition of the configured system having a number of inter-module communications to other partitions that exceeds the number of pins on the logic module of the partition and the logic module of the partition being configured to communicate through virtual interconnections in a time-multiplexed fashion through at least one pin of the logic module of the partition, the configurer determining a static virtual interconnection which includes a communication path extending through an intermediate reprogrammable logic module.
