Very High Speed Integrated Circuit Hardware Description Language (VHDL or VHSIC-HDL) is widely used in the industry for the description of digital electronic systems. VHDL is more verbose than other HDLs, can be a difficult language to learn and hence there is a need to make the process of implementation of digital electronic units via hardware description easier and quicker with minimum understanding of the language VHDL. This project entails the system development and implementation of a Graphical User Interface (GUI) capable of generating VHDL code for portmapping of a digital electronic system using a given datapath block diagram. The application was developed using Microsoft's Windows Presentation Foundation (WPF) framework and the Model-View-View Model (MVVM) pattern. Code generation was achieved using the Template based approach with the implementation Microsoft's Text Template Transformation Toolkit. Investigation results show that there exists a gap between the understanding and implementation of digital systems using VHDL. However, with the use of this project's port-mapping tool the results show the implementation process is made easier to the students of the department of Electrical and Computer Engineering of the University of the West Indies, St. Augustine.
