Abstract
An emulation system includes a first circuit for emulating a first logical part of a device, a second circuit for emulating a second logical part of the device that is different from the first logical part, wherein the first circuit is separate from the second circuit, and a third circuit connecting the first circuit and the second circuit to communicate signals between the first circuit and the second circuit.

An emulation system comprising:
- a first circuit for emulating a first logical part of a device;
- a second circuit for emulating a second logical part of the device that is different from the first logical part, wherein the first circuit is separate from the second circuit;
- a third circuit connecting the first circuit and the second circuit to communicate signals between the first circuit and the second circuit;
- and
- a controller generating a normal clock signal for output to the first and second circuits and a shift clock signal for output to the third circuit, wherein the shift clock signal is the normal clock signal shifted in phase,
- wherein the first and second circuits operate in sync with the normal clock signal and the third circuit operates in sync with the shift clock signal.
An emulation system comprising:
- a first circuit to emulate a first logical part of a device;
- a second circuit to emulate a second logical part of the device, wherein the first circuit is separate from the second circuit;
- and
- a time division connector connecting the first and second circuits to each other in a time division manner,
- wherein the time division connector transfers an output of the first circuit to the second circuit before activation of a normal clock signal input to the first circuit, the first and second circuits operate in sync with the normal clock signal, and the time division connector inputs a state value of the first circuit to the second circuit in sync with a shift clock signal input to the time division connector,
- wherein the shift clock signal is the normal clock signal shifted in phase.
A method of driving an emulation system with an emulation board including separate first and second emulators configured to respectively emulate first and second logical parts of a device, the method comprising:
- transferring verification data to the first and second emulators;
- operating the first and second emulators for a cycle of a normal clock signal output to the first and second emulators, wherein the first and second emulators operate in sync with the normal clock signal;
- and
- transferring a state value of the first emulator to the second emulator via a connection circuit in sync with a shift clock signal output to the connection circuit before an activation of the normal clock signal while sending output data of the first and second emulators to an external source,
- wherein the shift clock signal is the normal clock signal shifted in phase.
