Why Are Hardware Description Languages Important for Hardware Design Courses?

Curricula in computer engineering, computer science, and other related fields include several courses about hardware design. Examples of these courses are digital logic design, computer architecture, microprocessors, computer interfacing, hardware design, embedded systems, switching theorem, and others. In order for the students to realize the concepts taught in such courses, practical track should be reinforced along with the theoretical track. Many universities offer to their students labs in which they can practice hardware design. However, students need more than that: they need tools that enable them to design, model, simulate, synthesize, and implement hardware designs. Although high-level programming languages like Java and C++ could be an option, it might be a tedious task to use them for this mission. Fortunately, hardware-description languages (HDLs) have been specifically devised for this purpose. This paper shows some of the great features of HDLs and compare using them with using C++ for illustrating digital concepts through salient examples.
