This application provides a method, apparatus, terminal device, storage medium, and program product for chip operation detection. The method includes: acquiring real-time data streams of the data path according to a preset cycle during chip operation; invoking a preset comparison method to compare the real-time data streams with preset abnormal data streams to determine whether the real-time data streams and abnormal data streams are consistent; the abnormal data streams are data streams written into the monitoring unit after chip production and confirmed to cause errors; if consistent, determining a target avoidance method corresponding to the real-time data streams and invoking the target avoidance method to perform avoidance operations on the real-time data streams. This method can prevent errors caused by the chip continuing to run the real-time data streams and ensure the normal execution of the real-time data stream functions, thereby effectively detecting and avoiding errors that may occur during chip operation even after chip production, ensuring the safety and reliability of chip operation.
