VHDL (VHSIC Hardware Description Language) has served as a cornerstone of digital design for over three decades, enabling engineers to describe, simulate, and synthesize complex electronic systems. Yet despite its maturity, many VHDL designs suffer from a critical oversight: the code itself is rarely treated as a first-class engineering artifact. A VHDL description is source code, and VHDL designers can—and should—leverage the best practices of software development to produce high-quality work.
