Verilog is a hardware description language (HDL) that is used by designers to design and document electronic systems. An HDL is similar to a programming language but is not the same. It is used to design computer chips processors, CPUs, motherboards, and similar digital circuitry. Verilog is the most widely used HDL with more than 50,000 active designers using it for designing at various levels of abstraction.@ http://www.cetpainfotech.com/technology/system-verilog-Training
