Abstract- The VHDL generator tools aim is to translate designed component diagram to synthesizable VHDL code. The tools is web based, its provides a graphical user interface that allow the user to select a digital component, customize their parameter and generate the VHDL code. The reliability inception in this VHDL code generator is a probability method for measurement the tools in complicated parameters to be simplified. T o support the VHDL generator code tools, development of Graphic User Interface (GUI) is presented. Beginning with designing ideas of the interface within the tools based on principles of good interface design, the implementation of the design for the tools is to provide interface which address the needs of its users. Designing an interface for users its requires to deal with a number of issue. The user interaction mechanism with the tools is being the main concern to improve the tools interface for being able performed effectively with the user. The research study, its to developed graphic user interface of DiaHDL tools, which is able to provide both functional and aesthetic visualization in design. The graphical user interface is able to represent information into pleasing visualization.
