Error: can't read "safebit": no such variable

Description

You may get this error messages when executing the BSDL Customizer tcl files with unsupported devices. If you open the BSDL Customizer tcl files, the device string for newer devices is not available in the files. That is why you will see this safebit error during the extraction.  

For the newer devices, please use the Quartus® II software to generate the pre or post configuration BSDL files.
