Current Parallel DEVS simulation tools provide a wide set of debugging features. Omniscient debugging, or debugging backwards in time, is only rarely implemented, presumably due to its high resource consumption. Outside of DEVS simulation, omniscient debugging implementations are often lossy: some parts of the model or code are ignored, or they consider only a time window of most recent events....

To aid the development of spreadsheet debugging tools, a knowledge of end-users natural behaviour within the Excel environment would be advantageous. This paper details the design and application of a novel data acquisition tool, which can be used for the unobtrusive recording of end-users mouse, keyboard and Excel specific actions during the debugging of Excel spreadsheets. A debugging experim...

This paper describes the debugging and dynamic nwdijication facilities provided&nreal t ime distributed systems within the Testbed embedded systems environment. We exploit natural break-points present in a state machine programming model to pe$orm monitoring and debugging actions. This technique can avoid the probe ejJect which is a major problem in debugging concurrent and real-time systems. W...

The cost of writing debuggers is very high. Most debuggers are written employing low level operating system and hardware specific code, which is hard to port to new platforms or architectures and to extend with new debugging techniques. Moreover, current debuggers are usually limited in the amount of analysis that they perform and the level of detail that they provide in order to assist with de...
