ABSTRACT:
A system for physical emulation of electronic circuits or systems includes a data entry workstation where a user may input data representing the circuit or system configuration. This data is converted to a form suitable for programming an array of programmable gate elements provided with a richly interconnected architecture. Provision is made for externally connecting VLSI devices or other portions of a user's circuit or system. A network or internal probing interconnections is made available by utilization of unused circuit paths in the programmable gate arrays.
