FastScan and FlexTest Reference Manual, V8.6_4

Tools Supported: FastScan

Scope: All modes

Prerequisites: You can use this command only after FastScan flattens the design to

the simulation model, which happens when you first attempt to exit Setup
mode or when you issue the Flatten Model command.

SAVe FLattened Model filename [-Replace] [-Flat | -All]

Saves the flattened circuit model, the scan trace, and all DRC related information
to a specific file.

This command allows non-Falcon users of FastScan to quickly restore a new
session to the state of a previous session based on saved check point data. This
command lets you enter into ATPG/GOOD/FAULT modes without reading the
netlist, flattening, and performing DRC.

The Save Flattened Model command does not save pattern or fault list information
in the model file. However, you can utilize the Setup Checkpoint command to
save the pattern set and the fault list periodically.

When opening a previously stored model, FastScan defaults to the same system
mode as when the model was saved. It is also possible to save the flattened model
only (no scan chain or DRC data) to be restored into setup mode from any system
mode. You can use the -flat filename option of the Fastscan invocation command
to read a saved model. See the

 invocation command description on page

A required string that specifies the name of the file to which you want to write
the flattened circuit model.
