Report Feedback Paths

 

 

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:
