Verilog HDL Quick Reference Guide (56p)

EBook Description: The following Verilog HDL constructs are independent processes that are evaluated concurrently in simulation time: � module instances � primitive instances � continuous assignments � procedural blocks

Originally a modeling language for a very efficient event-driven digital logic simulator.
Later pushed into use as a specification language for logic
synthesis.
Now, one of the two most commonly-used languages in digital hardware design (VHDL is the other.
Virtually every chip (FPGA, ASIC, etc.) is designed in part using one of these two languages.

REVIEW OF VHDL

VHDL begin with double dashes (no space between them) and continue to the end of the current
line.

Introduction to ISE & ModelSim

After design entry (either schematic capture or VHDL entry),
ModelSim (Mentor Graphic Corp.) will be used to simulate and verify the design (with debugging performed as needed).

VHDL & Verilog Compared & Contrasted Plus Modeled Example Written in VHDL, Verilog and C

There are now two industry standard hardware description languages, VHDL and Verilog. The complexity of ASIC and FPGA designs has meant an increase in the number of specialist design consultants with specific tools and with their own libraries of macro and mega cells written in either VHDL or Verilog. As a result, it is important that designers know both VHDL and Verilog and that EDA tools vendors provide tools that provide an environment allowing both languages to be used in unison.

VHDL Cookbook - a 111 page PDF pre-published version of The Designer's Guide to VHDL

VHDL is a language for describing digital electronic systems. It arose
out of the United States Government�s Very High Speed Integrated Circuits
(VHSIC) program, initiated in 1980.

The Hamburg VHDL Archive - lots of stuff here including a good look at libraries and packages.

Since the early 80's our institute has been member of different research activities and projects dealing with system- and VLSI-design.

A VHDL tutorial with good examples and links to reference and related material.

HDL (Hardware Description Language) based design has established itself as the modern approach to design of digital systems, with VHDL (VHSIC Hardware Description Language) and Verilog HDL being the two dominant HDLs.
