Getting Started with Verilog
What are the best practices for writing efficient Verilog code?
Best practices include using descriptive variable names, organizing code into hierarchical modules, avoiding race conditions, and adhering to coding style guidelines.
Can Verilog be used for synthesis and simulation?
Yes, synthesis and simulation are two frequent uses for Verilog. While simulation tools simulate the behavior of Verilog designs to ensure accuracy and functionality, synthesis tools convert Verilog code into a netlist of logic gates.
What is the difference between Verilog-1995 and SystemVerilog?
SystemVerilog is an extension of Verilog that adds new features for verification and design, like classes, interfaces, and constrained-random testing. Verilog-1995 is the original version of Verilog. Additionally, SystemVerilog has improvements to make integrating with C/C++ programmes simpler.
Getting Started with Verilog
For a long time, computer programming languages like FORTRAN, Pascal, and C were used to describe computer programs and their code execution is sequential. But there isn’t any language to describe the digital circuits. This is when Hardware Description Language(HDL) came into play. HDLs are even popular for verification purposes. There are mainly two types of HDL:
- Verilog HDL
- VHDL (Very High-Speed was Integrated Circuit (VHSIC) Hardware Description Language)
Note: Verilog HDL and VHDL aren’t the same. VHDL was used before Verilog came into existence. the difference between them will be discussed in the later part.
