Despite the progress that has been made in the field of program visualization, programmers nowadays still rely on inserting extra code (e.g. print statements) to visualize complicated program states during debugging. There are many obstacles that have impeded and continue to impede program visualization for practical use. One such major obstacle is that a wide variety of data types and interpretations from data to visualizations are arbitrary. It is unlikely that visualizations will be available a priori to cover everything that might be of interest. In an attempt to address the problem, a debugging visualization tool called xDIVA is presented here. A practical application of xDIVA in EDA (Electronic Design Automation) industry is described. Demonstrations and tool download can be accessed at "http://oolab.csie.ncu.edu.tw/xDIVA".
