Often, the use of MARK_DEBUG is on pins of
hierarchies and can be used on any elaborated sequential element, such as RTL_REG. MARK_DEBUG
attributes are intended to go on nets. It is recommended that you use both the get_nets and the get_pins
command as shown, such as.
set_property MARK_DEBUG true [get_nets -of [get_pins\ hier1/hier2/<flop_name>/Q]]This recommended use ensures that the MARK_DEBUG goes onto the net connected to that pin, regardless of its
name.
Note: If a
MARK_DEBUG is
applied on a bit of a signal that was declared as a bit_vector, the whole bus gets the
MARK_DEBUG attribute. In addition, if a MARK_DEBUG is placed on a pin of a hierarchy, the full
hierarchy is kept.
