A safe operating region of a complex integrated circuit may be determined by selecting an operating point for the integrated circuit (IC) at a first voltage and first frequency. A test program is executed by a central processing unit (CPU) comprised within the IC to test a portion of the IC. Communication activity between the IC and a host system is recorded to form a data log while the test program is being executed. A crash is detected by storing and examining the data log periodically, and assuming that the test program has crashed when any one of a predetermined set of crash conditions is detected during examination of the data log. The operating point may be iteratively changed and execution of the test program repeated while continuing to check for a crash until a crash is detected. |
