Abstract
PURPOSE:To realize an easy and high-speed process of diagnosis to a device to be observed, by storing successively the internal state and having a storing operation of state history for the time designated previously even after the prescribed stop conditions are detected. CONSTITUTION:A control circuit 120 replaces an address counter 140 every time a trace condition detecting circuit 110 detects the trace conditions. At the same time, the state history information 131 of a device to be observed is written into an address designated by the counter 140 of a storage circuit 130. When the conditions to complete the tracing action is detected by a stop condition detecting circuit 100, a signal 120 is delivered. The stop signal is delayed 152 by a delaying circuit 150 and by a time 151 that is previously designated. Then the tracing (state history storing) action is carried out. In such way, the tracing after detection of stop conditions to realize an easy and high-speed process of diagnosis to a device to be observed.
