Difference Between Verilog and SystemVerilog

Verilog vs. Systemverilog: What is the Difference?

The Verilog language is used by engineers to create hardware prototypes, while Systemverilog is created by software engineers because it’s much easier for them. The article breaks down the two languages and their differences – like what they’re used for and how much time it takes to develop an application using the different languages.

What is Verilog?

Verilog is an HDL-based hardware description language that can be used to describe and simulate circuits and systems. It was developed by Xilinx, Xilinx’s competition, Altera, Avermedia, and other companies in the late 1990s. SystemVerilog is a SISO-based hardware description language designed by Cadence Design Systems for modeling and simulating both digital and analog systems such as power supplies or meters.

What is Systemverilog?

Systemverilog is a formal language syntax used by Verilog to implement systems design. It is based on the SystemC open standard. Systemverilog is an extension of Verilog that is designed for software development. It was created with the intent to provide formal support for state machine design.

What are the Differences between the two?

The Systemverilog is a standardized language, which is a specification for a software-based system where the hardware and software are interfaced. The Verilog language was developed by Xilinx, Inc. in 2005 as a standardized language that would be used to describe the behavior of any digital system being developed. The Systemverilog is a superset of Verilog.

Conclusion

Systemverilog is a kind of object-oriented language that was developed by Cadence. The language allows developers to specify the operation of a system in functional terms rather than program flow. This makes it easier for users to reuse the design and build other designs from it. Verilog is a hardware-oriented language that can also be used for software, but it does not have the OO capabilities of Systemverilog.
