OPERATOR PRECEDENCE IN VERILOG

Operator Precedence:

                              The precedence of operators is shown below. The top of the table is the highest precedence and the bottom is the lowest. Operators on the same line have the same precedence and associate left to right in an expression. Parentheses can be used to change the precedence or clarify the situation. We strongly urge you to use parentheses to improve readability.
