4. Lexical Conventions

• Any Verilog HDL source code is created with the combination of IDENTIFIERS and KEYWORDS which are also called as SYNTAX/SEMANTICS. These are globally called lexical tokens. Combination of more than one lexical token originate LEXICAL CONVENTIONS.

• Lexical conventions are set of important methods and techniques to write and understand the Verilog HDL code with ease. ​

• Lexical tokens in Verilog HDL are given below:

4.1 white space requirements

4.2 comment implementation

4.3 operator usage

4.4 number representation

4.5 string handling

4.6 identifier declaration

4.7 keyword usage
