Popularity of Verilog HDL

Verilog HDL has evolved as a standard hardware description language. Verilog HDL offers many useful features for hardware design. The following is some useful features of Verilog HDL.

• Verilog HDL is a general-purpose hardware description language that is easy to learn and to use. It has a similar syntax to the C programming language. Designers with C programming experience will find it easy to learn Verilog HDL.
• Verilog HDL allows different levels of abstraction to be mixed in the same model. Thus, a designer can define a hardware model in terms of switches, gates, RTL, hierarchical design or behavior code and also stimulus module as trigger signals to test the design.
• Most popular logic synthesis tools support Verilog HDL. This makes it the language of choice for designers.
• All fabrication vendors provide Verilog HDL libraries for post-logic synthesis simulation. Thus, designing a chip in Verilog HDL allows the widest choice of vendors.
• The Programming Language Interface (PLI) is a powerful feature that allows the user to write custom C code to interact with the internal data structures of Verilog. Designers can customize a Verilog HDL simulator to their needs with the PLI.
