It provides a quick reference manual for the two most popular Hardware Description Languages (HDL): VHDL and Verilog. This app is written by engineers, for engineers. For every construct in VHDL, our app provides the nearest equivalent in Verilog, and vice-versa (or indicates if there is no direct equivalent).
Experienced custom digital logic designer for FPGA or ASIC? Electrical engineering student just learning the ropes? This app (which runs on iPhone and iPad) includes the following features
Searchable dictionary of every keyword, operator, and data type for both languages.
Handbook provides simple example for every single reference
Common functions in each language
All pre-defined attributes for VHDL (e.g., ‘leftof’)
All primitive gates and drive strengths for Verilog
Filter by language (VHDL, Verilog, or both)
Filter by language elements (keywords, operators, attributes, data types, etc.)
VHDL Ref is a new app for the iPhone, iPad, and iPod Touch. - [Link]
