VERIFICATION SYSTEM FOR VERIFYING SYSTEM LSI OPERATION,ETC.

摘要

A multiplexing block multiplexes and outputs a plurality of electric signals transmitting through a bus wiring. A demodulation block demodulates the plurality of electric signals multiplexed and output from the multiplexing block. By referencing the plurality of electric signals demodulated by the demodulation block, operation of the system LSI (1) is analyzed. Thus, with a number of output terminals smaller than the number of electric signals to be verified, it is possible to extract and analyze the electric signals of the entire system LSI. That is, it is possible to verify the operation of the entire system LSI with a reasonable cost and a simple configuration.
