Why is the checksum value generated by the Quartus II software programmer different than the checksum value generated by the Tcl checksum command?

Description

The checksums generated by the Quartus® II software and the Tcl checksum command are different because they are calculated using different algorithms. The checksum generated by the Quartus II software is calculated using a simple summation of the bytes of the programming/configuration data. The Tcl checksum command uses a different method of calculation (CRC-32 or Adler32) and calculates the checksum on the entire file.
