the format of these files is as follows:
| XlxV | magic start word |
| 37 | version number |
| E or D | Encrypted or Decrypted |
| M or B | Mimebase64 or Binary encoded |
even though somefiles have the 'E' for encrypted, they are not encrypted, just compressed, using zlib.
this little perl script will decompress xilinx files.
use like this, as a pipe, reading from stdin, output to stdoutperl xl_decode.pl <encoded.vhdor like this, specifying a src and output file
perl xl_decode.pl encoded.vhd decoded.vhd
