Abstract: The one or more processors of an electronic device execute program code. While executing the program code, measurements are performed on the electronic device to obtain first data. Further, execution of the program code is monitored to obtain second data, e.g., debug information. The measurements are coordinated with the monitoring of the execution of the program code.
