Advance Features of Hardware Description Language (VHDL) for Undergraduate StudentsVery High Speed Integrated Circuit Hardware Description Language or VHDL is a programminglanguage that allows an individual to define how a piece of hardware behaves. This language wasdeveloped first by US military and became IEEE standard in 1987. It was updated in 1993 and isknown today as "IEEE standard 1076 1993".The complexity of ASIC and FPGA designs has caused an increase in the use of hardwaredescription languages such as VHDL. As a result, it is vital that students learn the advancefeatures of this language. Companies like Xilinx, Altera, and Cadence have designed properhardware interfaces for the use of this language. These days every chip manufacturer starts onVHDL (or Verilog) before the company goes to actual production of IC. There are two aspects tomodeling hardware that any hardware description language facilitates: true abstract behavior andhardware structure. VHDL has three parts: Library, Entity, and Architecture.Despite reviewing many undergraduate digital books with VHDL contents, there were noreferences on how to define memory (array), files (input/output), subroutine, and so on. In thispaper author explains the use of several important VHDL features such as generic, component,array, and files.
