Recently, PLDs have replaced fixed function ICs in digital electronics application due to their advantages. VHDL is wideI); used in prog/"{/mming PLDs stich as CPLD and FPGA among others. Introduction to VHDL, will give an advantage to future engineers for their career development. Since VHDL is a hardware description language, the teaching and learning process l11ust be intuitive enough to help students to gain beller understanding. Xilin, ISE software is one of" the synthesizers available and used in the industry. An interactive and animated teaching aid has been developed to employ the advantages ofe-Iearning pedagogy so as to optimize the teaching and learning process. This paper is to present the developed leaching aid and its interactive features in assisting users in designing simple application of digital systems using VHDL (text entry) on PLDs platform.
