| Description |
The tf port declaration BNFs are defined as follows: tf_input_declaration ::= input [ reg ] [ signed ] [ range ] list_of_port_identifiers | input [ task_port_type ] list_of_port_identifiers tf_output_declaration ::= output [ reg ] [ signed ] [ range ] list_of_port_identifiers | output [ task_port_type ] list_of_port_identifiers tf_inout_declaration ::= inout [ reg ] [ signed ] [ range ] list_of_port_identifiers | inout [ task_port_type ] list_of_port_identifiers task_port_type ::= time | real | realtime | integer Two notes: A. In each of the declarations, both productions are possible when none of the optional parts are used, e.g., input list_of_port_identifiers. That could be fixed by removing the brackets around 'reg' or around 'task_port_type'. B. In tf_inout_declaration, in "inout [ task_port_type ]", the left square bracket after 'inout' is incorrectly bold. It should be non-bold. |
| Fix |
In A.2.7 and in Syntax 10-1 of 10.2, delete the square brackets from each occurrence of [ task_port_type ] |

Can't do it by removing the brackets around 'reg'. That would disallow things like input signed a; output [7:0] b; inout signed [3:0] c; which are currently legal. But removing the brackets around 'task_port_type' should work. Or leave it alone, since it is not wrong.
