DEBUG CIRCUIT, DEBUGGER DEVICE, SEMICONDUCTOR DEVICE, AND DEBUG METHOD

摘要

PROBLEM TO BE SOLVED: To improve debug work efficiency.SOLUTION: A storage section 2a stores a first code value which is calculated by a coding system where a value changes in response to a signal sequence in a circuit 3 to be debugged, and indicates a stop condition of the circuit 3. A code value calculation section 2c calculates a second code value by the coding system, every time a signal in the circuit 3 changes, on the basis of the signal. An operation stop section 2d stops operation of the circuit 3 when the first code value coincides with the second code value.SELECTED DRAWING: Figure 1
