.. code-block:: vhdl

   WR_EN_OUTPUT : WR_EN(parameter);

**Fix**

.. code-block:: vhdl

   WR_EN(parameter);

procedure_call_002
##################

|phase_1| |error| |structure|

This rule checks for labels on concurrent procedure call statements.
Labels on procedure calls are optional and do not provide additional information.

**Violation**

.. code-block:: vhdl

   WR_EN_OUTPUT : WR_EN(parameter);

**Fix**

.. code-block:: vhdl
