| Release | 2001b: A.2.7, 10.2.1 (Syntax 10-1)
|
| Environment |
|
| Description |
The LRM gives this syntax for task: task_declaration ::= (From Annex A - A.2. ) TASK [ AUTOMATIC ] task_identifier ; { task_item_declaration } statement ENDTASK In fact, it should be statement_or_null, not statement, since verilog-xl accepts a task with a null statement: module m; task t; ; endtask endmodule |
| Fix |
In Syntax 10-1 of 10.2.1 and in A.2.7, change each of the four occurrences of "statement" to "statement_or_null" Note that this change applies ONLY to tasks and NOT to functions, because functions MUST contain at least one statement, an assignment to the function output. |
