[ Team LiB ] Popularity of Verilog HDL Verilog HDL has evolved as a standard hardware description language. Verilog HDL offers many useful features | Team LiB Popularity of Verilog HDL Verilog HDL has evolved as a standard hardware description language. Verilog HDL offers many useful features Verilog HDL is a general-purpose hardware description language that is easy to learn and easy to use. It is similar in 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 or behavioral code. Also a designer needs to learn only one language for stimulus and hierarchical 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 postlogic 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. Team LiB Team LiB Trends in HDLs The speed and complexity of digital circuits have increased rapidly. Designers have responded by designing at higher levels of abstraction. Designers have to think only in terms of functionality. EDA tools take care of the implementation details. With designer assistance EDA tools have become sophisticated enough to achieve a close-to-optimum implementation. The most popular trend currently is to design in HDL at an RTL level because logic synthesis tools can create gate-level netlists from RTL level design. Behavioral synthesis allowed engineers to design directly in terms of algorithms and the behavior of the circuit and then use EDA tools to do the translation and optimization in each phase of the design. However behavioral synthesis did not gain widespread acceptance. Today RTL design
