1. An arrangement of electrically reconfigurable logic assemblies for use in an electrically reconfigurable hardware emulation system which can be configured with a circuit design in response to the input of circuit information, said arrangement of electrically reconfigurable logic assemblies comprising: at least two electrically reconfigurable logic assemblies, each of said electrically reconfigurable logic assemblies including a plurality of reprogrammable logic devices, each of said reprogrammable logic devices having internal circuitry which can be reprogrammably configured to provide functional elements selected from the group of at least combinatorial logic elements and storage elements, each of said reprogrammable logic devices also having programmable I/O terminals which can be reprogrammably connected to said functional elements configured into said reprogrammable logic devices; each of said electrically reconfigurable logic assemblies also including a first plurality of reprogrammable interconnect devices, each of said first plurality of reprogrammable interconnect devices having a first group of I/O terminals connected to said programmable I/O terminals of each of said reprogrammable logic devices and internal circuitry which can be reprogrammably configured to provide interconnections between said first set of I/O terminals, each of said first plurality of programmable interconnect devices also having a second group of I/O terminals; and a second plurality of reprogrammable interconnect devices connected to said second group of I/O terminals on said first plurality of reprogrammable interconnect devices in each of said electrically reconfigurable logic assemblies, whereby selected functional elements configured into selected ones of said plurality of reprogrammable logic devices in one of said electrically reconfigurable logic assemblies can be reconfigurably interconnected to selected functional elements configured into selected ones of said plurality of reprogrammable logic devices in another of said electrically reconfigurable logic assemblies.
