VHDL Ref vs VHDL Manual

The pocket translator for hardware description languages. VHDL Ref is a quick reference for VHDL, Verilog, and SystemVerilog, written by engineers for engineers. For every construct in VHDL it shows the equivalent in Verilog, and vice versa. Whether you are an FPGA or ASIC designer who thinks in one language but has to read the other, a verification engineer working in SystemVerilog, or an engineering student in your first digital design course, VHDL Ref puts the answer one tap away. + 328 entries covering every keyword, operator, and data type in both languages + Cross-language equivalents on every entry: see how the other language says it + A simple worked example for every single entry + SystemVerilog coverage, plus VHDL 2008 and Verilog 2001 notation + All pre-defined VHDL attributes + All Verilog primitive gates and drive strengths + Filter by language and by element type + Works completely offline: in the lab, on a plane, behind the firewall + No ads, no subscription, no account, no tracking Native on iPhone, iPad, and Mac (a real Mac app, not a port), so the same reference sits next to your simulator at your desk and rides in your pocket everywhere else. Note: VHDL Ref is a reference, not a simulator or compiler. It is the book you keep open beside your tools, rebuilt for the device you always have with you.

VHDL Manual is a fast, offline reference built for engineers and students who use VHDL in real projects; optimized for iPhone and iPad. Explore a growing library of 276 concepts with clear explanations and practical code examples. • Browse a structured manual by topic, or use smart search with ranked results. • Jump between related concepts to move from “what is this?” to “how do I use it?” quickly. • Bookmark key sections, track your recent history, and pick up where you left off. • Read examples with VHDL syntax highlighting, copy snippets, and share sections with teammates. • Add the "VHDL of the Day" widget to your Home Screen for a daily keyword or concept. Offline-first by design: the core manual is bundled in the app, so your reference is always available, even without an internet connection. We’re actively developing VHDL Manual and will keep expanding the library with new concepts and improvements.
