Report Feedback Paths
Tools Supported: DFTInsight, FastScan, and FlexTest
Scope: All modes
Prerequisites: You can use this command only after the tool performs the learning
process, which happens immediately after flattening a design to the simulation
model. Flattening occurs when you first attempt to exit Setup mode or when
you issue the Flatten Model command.

Usage
REPort FEedback Paths
DFTInsight Menu Path:
Display > Additions: Loops
Description
Displays a textual report of the currently identified feedback paths.
The Report Feedback Paths command lists the identification numbers of any
feedback paths that the tool identified during the last circuit learning process.
These feedback paths include, by default, any duplicated gates. You can suppress
duplicated gates by using the Set Loop Duplication command prior to initiating
the circuit learning process.

As stated earlier, the Report Feedback Paths command displays all the feedback
path identification numbers. You can use these identification numbers with the
Add Display Loop command to schematically display specific feedback paths.
When you issue the Add Display Loop command for specific feedback paths,
DFTInsight transcripts the same information as the Report Feedback Paths
command but, only for the paths that you specified.

Examples
The following example invokes the optional schematic viewing application,
leaves the Setup mode (which, among other things, flattens the simulation model
and performs the learning process), displays the identification numbers of any
learned feedback paths, and then schematically displays one of the feedback
paths:
