For a gate whose output is constrained to a fixed value, the tool reports only other gates whose output is also constrained. For a gate whose output is not constrained to a fixed value, the tools reports only other gates whose outputs are not constrained. During backwards tracing, a mux input, which is always blocked by a constrained value on the select line of the mux, will never be back traced.

Note or
∙
An optional switch that reports on the path between the first gate_id# pin_pathname and the second gate_id# pin_pathname. All paths must be specified at the primitive level. Paths do not extend through sequential elements. The output generates a report on each primitive in the path(s), in order of increasing gate_id#.
∙-Depth (FlexTest Only)
An optional switch that extends the cone report to several levels. The next level cones reported will be the cones of the endpoints of the previous level. If there are loops in a circuit, gates may be repeated in several levels. The default is only one level.
