String Literals
|
|
|
A string literal is enclosed in quotes and has its own data type. A string literal must be contained in a single line unless the new line is immediately preceded by a \. Non-printing and other special characters are preceded with a backslash. String literals can also be cast to a packed or unpacked array. SystemVerilog added following special string characters. |
