Timing Diagram Markup Language (TDML), Version 1.1-1-051899
Attribute:    driven   (Driven)
Definition:

This attribute specifies whether a Signal <signal> is being used as an input or an output at the time associated with the given Edge <e>.

Use:

When a Timing Diagram <timing.diagram> is describing a particular component, "driven" means the component is driving the Signal's <signal>'s state. If the attribute is set to 1, the Signal <signal> is being used as an output (driven by the component under consideration).

Attribute Content:
Value

Meaning

0

Signal is an input at associated edge.

1

Signal is an output at associated edge.

Any other number

Signal is an output at associated edge.

Associated Elements:

This attributed is associated with:

Remarks:

This attribute only has meaning for Signals <signal>s with a "conn.type" attribute value of IO (IO indicates an Input/Output signal, also known as a bi-directional signal). The edges of a signal with a "conn.type" attribute of O (O indicates Output) are implicitly driven. The edges of a signal with a "conn.type" attribute of I (I indicates Input) are implicitly not driven.

A value of 1 is assumed if this attribute is not specified on an Edge <e> of an IO signal.
