Abstract

A resource board for a circuit emulator holds programmable logic devices (PLDs) and other emulation resources such as random access memories (RAMs) and employs both hard-wired and network-based virtual signal paths to flexibly route signals between the emulation resources on the resource board and resources mounted on other resource boards, workstations and other external equipment. The resource board also provides the logic and balanced signal paths needed to deliver clock signals to the PLDs and reduces the number of signals needed to communicate with external test equipment by implementing much of the pattern generation and data acquisition functionality needed to test an emulated circuit.
