Right. If you say "The arguments cannot be expressions of the string type," it means *all* the arguments.

It is allowed. -- Brad ________________________________ From: owner-sv-bc@eda.org [mailto:owner-sv-bc@eda.org] On Behalf Of Bresticker, Shalom Sent: Monday, May 14, 2007 7:11 AM To: sv-bc@eda.org Subject: [sv-bc] D3 20.2.1: $display arguments In Draft 3, 20.2.1, Stu has combined 1364 and 1800 to his understanding as follows: The $display and $write tasks display their arguments in the same order as they appear in the argument list. Each argument can be a quoted string literal, an expression that returns a value, or a null argument. The arguments cannot be expressions of the string data type, with the exception that the argument corresponding to a string % format specifier (s) may have the string data type. This is subtly different from 1800-2005 22.13, which says, - The format arguments to these tasks must be string literals, i.e., they cannot be expressions of string data type. The only exception is $sformat, whose second argument can be an expression of string data type. - The first argument of $swrite can be a string variable. - The integer % format specifiers (h, d, o, b, c, u, and z) may be used with any of the SystemVerilog integral data types, including enumerated types and packed aggregate data types. They shall not be used with any unpacked aggregate type. - The argument corresponding to a string % format specifier (s) may have the string data type. This says that the *format* arguments cannot be expressions of string data type. It does not say that about all arguments. What about $display (string);? Does anyone claim this is not allowed?
