∙-Backward

An optional switch specifying that the trace from the given objects is backward, towards the primary input pins.

If you do not explicitly specify a stopping_point switch in combination with this switch, the command default is for the backward trace to include only one level of gates.

The stopping_point is an optional switch argument that specifies the last gate that you want DFTInsight to include in the display. The following information describes the choices, from which you can select only one:

∙-Levelnumber

An optional switch and integer pair that specifies for DFTInsight to stop the trace after it reaches the given number of connected gates. If you do not use one of the stopping_point arguments with the command, the default is -Level 1. You can use this switch in combination with either the -Forward or -Backward switch.

∙-Cone

An optional switch that specifies for DFTInsight to stop the trace after it reaches all the gates in a cone of a clock. A cone is bound by tie gates, state elements, primary inputs, and primary outputs. This switch requires that you specify the direction in which DFTInsight performs the trace by using either the -Forward or -Backward switch.

∙-End_point

An optional switch that specifies for DFTInsight to continue the trace until it reaches either a primary input, primary output, or a tie gate. This switch requires that you specify the direction in which DFTInsight performs the trace by using either the -Forward or -Backward switch.

∙-Decision_point

An optional switch that specifies for DFTInsight to continue the trace until it reaches a multiple-input gate. The trace includes all the inputs of the multiple- input gate, but stops after that point. This switch requires that you specify the direction in which DFTInsight performs the trace by using either the -Forward or -Backward switch.
