摘要: 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 reconfigurable logic system of the present invention 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. A logic analyzer for a hardware emulation system is also disclosed. The logic circuits necessary for executing logic analyzer functions is programmed into th e programmable resources in the logic chips of the emulation system.

摘要: A method and a structure provide emulation circuit implemented on a logic block module comprising clocked and unclocked field programmable logic devices (FPGAs). Software modules analyse the target logic circuit and impose delay constraints to require certain storage instances to be implemented on separate FPGAs so as to prevent hold time violation artifacts.
