Abstract

PURPOSE: To reduce the number of connecting pins between the objective circuit and tracer memory, by incorporating the tracer memory in the integrated circuit.
CONSTITUTION: Every time when the logic operation is finished for the logic circuit 2 in the integrated circuit 1, the timing signal (t) is output from the timing generation circuit 4 in the logic circuit 2 to the control circuit 5, the control circuit 5 outputs the log signal (l) to the tracer memory 6, and the line state at the end of logic operation is logged in the tracer memory 6. If an error is taken place in the logic circuit 2, the error detection circuit 3 outputs the error signal (e) to the control circuit 5. The control circuit 5 outputs the log function stop signal (s) to the tracer memory 6.
