Abstract

A hardware emulation system is disclosed which reduces hardware cost by time multiplexing multiple design signals onto physical logic chip pins and printed circuit board. The hardware emulation system comprises a plurality of reprogrammable logic devices, and a plurality of reprogrammable interconnect devices. The logic devices and interconnect devices are interconnected together such that multiple design signals share common I/O pins and circuit board traces through the use of multiplexing.
