Some customers can't find the ".fs3" files after running xACT 3D. They want to use the ".fs3" files as an input to xACTView.
The FS3 file can be used by Calibre xACTView to visualize the technology stack and design structures for your design in 2D and 3D views. This file is an intermediate file created by Calibre xACT/xACT3D that contains the technology stack and design structure information.
To write out the fs3 files, add PEX REPORT FS3 <directory_name> to your rules.
After your PEX run is completed, a file called fs_1.report.fs3 is saved in the specified <directory_name>. This file should be fed to xACTview using the following command:
xactview ‑fs3 <directory_name>/fs_1.report.fs3
Important note: The <directory_name> must be an existing directory. If the <directory_name> path does not exist, the directory is not created and the FS3 file is not saved.
