The following are the reserved words per IEEE Standard 1800. Although not all will be implemented in all design automation tools, none should be used for identifiers.
Verilog is case sensitive. To be recognized as a keyword, these words must be all lower case. The code in Figure A.1 uses capitalized keywords as identifiers. Any temptation to use this technique should be resisted.
