The present invention is to provide an emulator and a method of emulation for using testing a system having complex interfaces capable of stable testing can be realize under the system regulation frequency or less frequency without using the high-performance and expensive tester. The emulator comprises a content addressable memory (CAM) configured to store addresses accessed by a system to be tested, a memory unit having storage area corresponding to the entry of the CAM, configured to store data corresponding to the address stored in the CAM, and test information for emulation, a shift register configured to store data and test information from a tester and transfer the data and the test information to the CAM and the memory unit, and a state machine configured to receive a request from a system or a tester and control transferring between a system and a tester.
