Abstract
In the conventional semiconductor device, it is impossible for two CPUs to operate memories to be debugged at synchronous timings. According to one embodiment, the operation verifying program analyzes the operation verifying command received by the first semiconductor devicefrom the external deviceby its own device (S), transfers the operation verifying command to the second semiconductor device(S, S), also analyzes the operation verifying command in the second semiconductor device(S), outputs the trigger signal (S, S) to the first semiconductor devicefrom the second semiconductor devicebased on the result of the analysis, writes the memory setting values included in the operation verifying command to the memories in the respective semiconductor device (S, S) based on the trigger signal, and restarts the device operation based on the written memory setting values.
