[[alternative]]High-Level Computer-Aided Debugging Tool

[[abstract]]Nowadays, debuggers are a standard part of every programming environment. Typically debugging functionality includes setting breakpoints, stepping line by line, watching variable values, etc.. Moreover, most debuggers also provide graphical user interface (GUI) which allows users to use mouse and invoke these functionalities. However, the basic of debugging techniques have changed little. A typical routine is to repeat steps such as set breakpoints, run the program to hit the breakpoints, and print variable values until the cause of defect is found. HILCADT is a state-of–the–art debugging tool which is implemented in java. It provides a high-level debugging language that is more expressive and flexible than the primitive language of debuggers. HILCADT sets breakpoints and continues programs automatically according to a given expressive query. HILCADT can be used to explore the temporal relation of variable’s values in a period of time and for further analysis. In addition, HILCADT can displays the debugging information on the HILCADT’s panel or uses DIVINE[11] to display debugging information in a 3D environment, which helps users to understand complicated data structure easily.
